Egypt and the Flood Date

"In purely Egyptian terms, a Menes can be set at c. 3100 BC, c. 3000 BC or c. 2900 BC." — Kenneth Kitchen, 1991¹

"Based upon the information currently available, we don't think it is even possible to be definitive about this. The only thing we can be certain about are the biblical dates and the age of the earth. It is Egyptian chronology that needs adjusting." — Gavin Cox and Gary Bates, Creation Ministries International, 2020²

"Currently, a biblical recalibration curve for carbon dates does not exist so we can only talk in generalities." — Robert Carter, Creation Ministries International, 2021³

Summary

Egyptologists date Djoser, who built the Step Pyramid at Saqqara, to about 2650 BC.  Ussher's chronology puts Noah's Flood at 2348 BC.  Answers in Genesis states the conflict in one sentence:  "pyramids could never withstand a worldwide flood."⁴  So either the Egyptian dates are wrong by three centuries or more, or the Flood was earlier than Ussher said.  This article tests both.  The findings run against the popular creationist case, and they show one honest way out that the popular writers have declined.

Against a Masoretic-date Flood.

1. The Old Kingdom is not dated by the Sothic cycle. Nearly every creationist treatment attacks Sothic dating. Kitchen counts exactly two pharaonic Sothic dates, and both are second-millennium.¹ The standard handbook says the Early Dynastic period rests on the Annals stone and the period from about 2350 BC down on lunar dates.⁵ Grant every word of the Sothic critique and the Old Kingdom does not move.
2. Two clocks that share no assumptions agree to within 178 years across more than 1,500 years of Egyptian history. The historical clock is dead reckoning of regnal years from 664 BC. The radiocarbon clock counts atoms in short-lived plants on a tree-ring calendar. Computed here, the gap between them runs from 20 years at the start of Dynasty 18 to 178 years at the accession of Aha. To put Djoser after Ussher's Flood, the king lists must be 244 years too long and the radiocarbon 312 years too old, for unrelated reasons.
3. Every new physical measurement has pushed early Egypt further from a Masoretic Flood, not nearer. Radiocarbon on 211 short-lived samples put Djoser at 2676–2643 BC,⁶ "earlier than some previous historical estimates."⁶ A 2025 study concluded "the Low Chronology is no longer empirically supported for the Old and Middle Kingdoms."⁷ Radiocarbon on 186 Predynastic and First Dynasty samples put the accession of Aha at 3111–3045 BC.⁸
4. The dynastic-overlap scheme fails on raw data. Courville and Habermehl run Dynasty 6 alongside Dynasty 12. Uncalibrated radiocarbon on comparable short-lived material puts the two about 350 radiocarbon years apart. Old Kingdom blocks were quarried to build a Twelfth Dynasty pyramid temple at Lisht.¹
5. The oldest astronomically fixed Egyptian date is about 2321 BC, year 1 of Wenis. That is later than every Masoretic Flood date. What kills a Masoretic Flood is what must fit above it: Dynasties 1 through 4, the unification of Egypt, the invention of writing, the Step Pyramid and all three Giza pyramids. Ussher's date leaves 27 years for all of it.
6. Every creationist founding date for Egypt traces to a late Christian chronographer, not to Egyptian evidence. Answers in Genesis' 2188 BC rests on Constantine Manasses, a Byzantine verse chronicler of the 1160s AD.⁴ The licence to overlap dynasties comes from Eusebius, and opens with the words "But if the number of years is still in excess."⁹

For the creationist side.

7. The Septuagint's Flood date, about 3298 BC, puts Djoser and Aha after the Flood on the mainstream chronology with no revision at all. Down and Ashton saw this escape and declined it on textual grounds.¹⁰ Anne Habermehl took it in 2013, for exactly the reason given here.¹¹ The popular writers do not raise it.
8. The mainstream concedes real slack at the top. The handbook says the contemporary dates "do not suffice to establish a coherent chronology for Dyns. 1–3."⁵ Kitchen puts the margin at the Archaic period above 200 years.¹ The 2025 radiocarbon study ruled out the handbook's own Old Kingdom dates at 95%.
9. The creationists closest to the problem say they cannot solve it yet. CMI withdrew its endorsement of David Down's chronology in 2022.¹² Carter says a biblical recalibration curve for carbon dates "does not exist."³ Habermehl's 2023 synchronisation, the most careful in print, never dates the Flood.

The hard residue.  No Flood date in play rescues the Predynastic.  The Badarian and Naqada farmers are radiocarbon-dated to 4400–3100 BC.⁸  The Septuagint rescues the pyramids and the First Dynasty.  It does not rescue the farmers before them, and no published creationist chronology of the Predynastic exists.

Part 1: Which Flood date, and what has to fit after it

The Flood date is not one number.  It depends on which text of Genesis 5 and 11 is followed, and the sibling article Genesis genealogies and gaps works through the options.  Four figures matter here.

The creationist camp itself does not agree to better than about 170 years.  Answers in Genesis prints 2348 BC.  CMI prints "the Great Flood (c. 2450 BC)."¹³  The Masoretic plain sum gives 2518 BC.  Chris Hardy and Robert Carter, writing in Journal of Creation, put the biblical bounds on creation at 5665 to 3822 BC and say "The Masoretic/LXX debate creates a 1,326-year dichotomy."¹⁴  They add a warning their own colleagues have not always heeded:  "Christians should avoid dogmatic claims of dating precision greater than intended by the Bible that could be refuted with new evidence, causing some to mistakenly believe the Bible itself has been refuted."¹⁴

Whatever the Flood date, Egypt has to start after it.  Genesis 10 makes Mizraim, Egypt, a grandson of Noah, and the dispersion from Babel comes later still.  The creationist writers therefore need Egypt's first king within a century or two of the Flood.  Here is what they print.

• Answers in Genesis (Elizabeth Mitchell): "Mizraim, Noah's grandson, founded Egypt around 2188 B.C., a date consistent with both biblical and secular records."⁴
• Ashton and Down, Unwrapping the Pharaohs: a caption runs the two chronologies side by side, "REVISED DATES: 21st C B.C. TRADITIONAL DATES: 2920-2770 B.C. KING MENES."¹⁰ Their text says "The history of Egypt would begin soon after the dispersion from Babel, around 2100 B.C."¹⁰
• Courville, The Exodus Problem, the ancestor of all of them: the interval from Flood to Dispersion needs no more than 200 years, "and that a period of 25-45 years shorter than this is entirely probable,"¹⁵ with Menes following at once. On Ussher's numbers that is Dynasty 1 at about 2190–2210 BC.

Set those against the mainstream.  Kitchen puts Dynasty 1 from 3000 BC.¹  The standard handbook puts Nar-mer "around 2950 BC."⁵  Radiocarbon puts Aha at 3111–3045 BC.⁸  The creationist founding date is 750 to 900 years later than any of them.  The rest of this article asks whether any part of that gap can be closed honestly.

Where do the creationist founding dates come from?  Not from Egypt.  Mitchell's footnote for 2188 BC reads in full:  "Ibid. The 12th-century historian Constantinus Manasses wrote that Egypt endured for 1,663 years. Egypt lost her independence around 526 B.C. with the Persian conquest. Hence, 2188 B.C. is a reasonable date for Egypt's founding and is consistent with a 2242 B.C. date for the Tower of Babel."⁴  Constantine Manasses was a Byzantine court poet who wrote a verse chronicle in the 1160s AD, about 3,300 years after the event.  No Egyptian document, excavation or measurement enters the calculation, and the cross-check is Ussher's Babel date.  Down and Ashton's authority is Eusebius, a fourth-century bishop:  "The ancient historian Eusebius thought so. He wrote, 'Egypt is called Mestraim by the Hebrews; and Mestraim lived not long after the flood…'"¹⁰  These are Christian chronographers fitting Egypt to Genesis.  They are evidence of what Christians believed in AD 325 and 1160, not of when Egypt began.

Part 2: How the Old Kingdom is actually dated

Almost every creationist treatment of Egypt attacks the Sothic cycle.  Mitchell:  "In reality, there is no evidence for this Sothic cycle in ancient Egypt."⁴  Bates:  "it would be unwise to date chronologies by any Sothic cycle."¹³  Douglas Keenan, a mathematician with no creationist stake, argues that "Sothic dating is not valid for the Middle Kingdom."¹⁶  Much of this is fair.  Krauss, who wrote the handbook's Sothic chapter, gives the Illahun date a 52-year spread on its own:  "the Illahun Sothic date corresponds to any year between ca. 1882 and 1830 BC."⁵

None of it touches the Old Kingdom, for a simple reason.  There is no Old Kingdom Sothic date.  Kitchen:  "One is the rarity of such dates in our existing texts. One exists under Sesostris (II or III) of the twelfth Dynasty, another under Amenophis I in the early eighteenth Dynasty."¹  Two dates, both second-millennium.  The handbook's chronological table says in its headnote what the early periods rest on instead:  "For the Early Dynastic Period chronology is based on the Annals stone (Chapter I. 1); for the period between ca. 2350 and 750 BC on lunar dates (Chapter III. 8)."⁵  Keenan himself concedes the point in his fifth conclusion:  "The internal chronologies of the three kingdom periods do not depend on Sothic dating. As such, the internal kingdom chronologies are unaffected by the present work."¹⁶

Four things carry the Old Kingdom, in order of strength.

Dead reckoning from 664 BC.  Egyptian dates are exact from the accession of Psammetichus I, fixed to the year by Ptolemy's canon and the Assyrian record.  The sibling article on Mesopotamian absolute chronology shows why:  the Assyrian eponym canon runs unbroken from 911 to 648 BC, pinned by the solar eclipse of 763 BC.  From 664 BC the Egyptologist counts attested regnal years upward.  Kitchen's summary:  "So, from about 30 years in 2000 BC, through 20/10 years by 1500 BC, to 11 years in the thirteenth century BC and less into the first millennium BC, dates come exact from 664 BC."¹  Every year a revisionist deletes above 664 BC must go without breaking the Egyptian-Assyrian synchronisms below.  The schemes that try are the subject of Dating the Exodus.

A lunar chain.  Egyptian documents record lunar-calendar dates against the civil calendar.  A pair of lunar dates in the Fifth Dynasty Abusir papyri, found by Posener-Kriéger, can be linked to a lunar date at Khozam in the early Eleventh Dynasty.  Krauss and Warburton:  "the appropriate lunar distance between year 7 of Wenis and the Khozam date amounts to at least 211 years + 119 days; other astronomically feasible possibilities are 236 y + 119 d or 261 y + 119 d.  The corresponding possibilities for year 1 of Wenis can be expressed as 2321 BC ± 25 years."⁵  The ±25 printed on every Old Kingdom line of the handbook's table is the spacing between admissible lunar solutions, not a vague guess.  This is the oldest astronomically anchored Egyptian date.

The Annals stone.  The Palermo Stone and its fragments once listed every year of every early king with its events.  The handbook's editors reconstruct about 355 years for Dynasties 1 to 3 from it, then warn:  "The reliability of any sum is, however, open to question; whereas the order of succession as preserved in the Annals conforms to contemporaneous data, its relevance for counting regnal years remains conjectural."⁵  A creationist is entitled to that sentence.  Note what it does and does not concede.  The sum is conjectural.  The order matches the contemporary evidence.

The Turin Canon.  Ryholt calls it "the only true king-list preserved from ancient Egypt before the Ptolemaic period."⁵  It was "written on the reverse of a discarded tax register dating to the reign of Ramesses II," about 1,300 years after the reigns it lists.⁵  Its archaic section is the fullest and the worst.  "The royal names in this section are the most severely corrupted,"⁵ and "the text should be treated with circumspection."⁵

Manetho, whose dynasty totals the creationist writers spend most of their effort attacking, is not on this list.  He is a cross-check, dropped where he conflicts:  "It is generally agreed that the TC's 30 years, and Manetho's 33 years for Onnos (Wenis) are far too high."⁵

The earliest firmly dated Egyptian material

Both sides overstate this, so here it is precisely.

Two things follow.  First, the oldest date fixed by an independent astronomical observation is year 1 of Wenis, about 2321 BC.  That is 27 years after Ussher's Flood, 129 after Bates', and 197 after the Masoretic plain sum.  The anchor by itself does not contradict a Masoretic Flood.  Second, everything above the anchor is Dynasties 1 through 4:  the unification of Egypt, the earliest hieroglyphic writing, the Step Pyramid, and the three Giza pyramids.  Ussher's date gives all of that 27 years.  The Annals reconstruction gives Dynasties 1 to 3 alone 355 years.  Africanus' Manetho gives Dynasties 1 and 2 alone 555 years.⁹  Radiocarbon gives Dynasty 1 by itself 170–270 years.⁸  This reframing does not depend on radiocarbon at all.  Grant the creationist the lunar anchor and Ussher's Flood, and ask him to fit four dynasties into 27 years.

Part 3: The two-clock test

Egyptian absolute dates come from two clocks that share no assumptions.  Clock A is the historical one:  dead reckoning of attested regnal years from 664 BC, braced by the lunar dates above.  It uses no physics.  Clock B is radiocarbon on short-lived plant material, calibrated against tree rings.  Its calendar axis owes nothing to king lists.  Bayesian models use reign lengths as priors, but the measurements themselves are counts of atoms.

Creationists propose two routes to a shorter Egypt.  Route (a) says Manetho's dynasties overlapped, so the king lists are too long.  Route (b) says carbon-14 was depleted after the Flood, so radiocarbon dates are too old.  Each route makes a prediction about the gap between the two clocks, and the gap can be measured wherever both have been published.  This is the article's own computation, in research/two-clock-test.ts.  The inputs are the handbook's chronological table and Kitchen's Table 2 for the historical clock, and Bronk Ramsey 2010's Tables S7 and S8, Dee 2013 and Erdil 2025 for radiocarbon.  Every radiocarbon figure is the 68% range.¹⁷

All dates BC.  "Gap" is the radiocarbon midpoint minus the historical date, in years;  positive means radiocarbon reads older.  The low historical column is Hornung, Krauss and Warburton;  the high is Kitchen.

Result 1.  Across more than 1,500 years the two clocks never diverge by more than 178 years.  Against the low chronology the gap runs from +20 to +178;  against the high one, from −54 to +88.  The gap does grow with age, which is the direction route (b) predicts.  A Masoretic Flood needs 600 to 1,000 years at Dynasty 1.

Result 2.  Neither route works alone.  Route (b) corrects radiocarbon and does nothing to the historical clock, which put Djoser at about 2600 BC before radiocarbon dating existed.  Route (a) shortens the king lists and does nothing to the atoms in the objects.  To land Djoser after the Flood, both clocks must be wrong, by similar amounts, in the same direction, for unrelated reasons.

The figures are against the low historical chronology;  against Kitchen's high one the king-list deletion at Ussher's date is 352 years.

Result 3.  The Masoretic plain sum is much less badly off than Ussher's date.  At 2518 BC the deficit at Djoser is 74 years of king list and 142 of radiocarbon, and 74 years is inside Kitchen's own ±100 for the Old Kingdom.  That is a real point for a creationist who drops Ussher's adjustments.  It does not help at Dynasty 1, where the deficit is about 380 years on the historical clock and 560 on radiocarbon.

What the computation does not do.  The gap is the difference of two published numbers, so it carries both sets of uncertainties:  the handbook's ±25, Kitchen's ±100 to ±200, and the width of each radiocarbon range.  Bronk Ramsey 2010's running text could not be obtained.  Its modelled dates could:  they are printed king by king in the paper's supporting material, which is free.⁶

Part 4: The dynastic-overlap route, tested

Manetho survives only in quotations by Josephus, Africanus, Eusebius and Syncellus.  The passage every creationist chronology rests on is Eusebius, at p. 9 of Waddell's Loeb edition:

"But if the number of years is still in excess, it must be supposed that perhaps several Egyptian kings ruled at one and the same time; for they say that the rulers were kings of This, of Memphis, of Sais, of Ethiopia, and of other places at the same time… Hence arose the great total number of years."⁹

Mitchell and CMI quote it accurately.  Two things follow.  First, the opening clause says what it is:  a fourth-century bishop offering a conjecture to bring Manetho's totals inside a biblical frame.  Eusebius was doing in the 320s what Answers in Genesis does now, and he says so.  It is not an Egyptian record of co-regency.  Second, the point is sometimes right.  Waddell's own footnote refers to the Piankhi stela, which shows several petty kings ruling at once.⁹  That stela is eighth-century BC, in the Third Intermediate Period, where Egyptologists themselves run parallel dynasties.  Africanus' Manetho gives the Thirteenth Dynasty "sixty kings of Diospolis, who reigned for 453 years,"⁹ and no Egyptologist uses that figure.  The critique of Manetho is aimed at a chronology nobody now builds.

The question is whether overlap can be run inside the Old Kingdom.  Two creationists have worked that out in detail.  Donovan Courville's The Exodus Problem (1971) is the ancestor of the rest.  His fifth point:  "The so-called Middle Kingdom of Egypt thus never had an existence as such and is but a creation of modern historians resulting from an erroneous interpretation of Manetho's dynasties."¹⁵  He runs Dynasty 6 alongside Dynasties 12 and 13, merges the two Intermediate Periods, and follows with "If Dynasty VI was parallel to Dynasty XII, then the Pyramid era of Dynasties III to V must have just preceded Dynasty XII as well as Dynasty VI."¹⁵  Anne Habermehl is the second.  Her 2013 conference paper states the scheme:  "Dynasties 5 & 6 may have run concurrently with Dynasties 11 & 12," with the First and Second Intermediate Periods treated as one event, and Dynasties 7 to 10 running alongside 13 to 17.¹⁸  Her 2023 paper in Answers Research Journal keeps that structure, with the Twelfth Dynasty ruling the north and holding "power over the pharaoh of the Sixth Dynasty, who ruled Upper Egypt (the south) under him."¹⁹

Both schemes are testable, and both fail three tests.

Raw radiocarbon.  Erdil and colleagues published new AMS dates in 2025.  Their Table 1 gives Fifth or Sixth Dynasty linen from Deshasheh at 3815, 3899 and 3915 radiocarbon years BP, from the pyramid of Pepy I at 3956, and from the pyramid of Merenre at 3968.  Their Table 2 gives Twelfth Dynasty reed and grass culms from Senusret III's fortress at Uronarti at 3528 to 3642 BP.⁷  These are uncalibrated measurements on comparable short-lived plant and textile material, before any model or curve is applied.  The Old Kingdom set averages about 350 radiocarbon years older than the Middle Kingdom set, and even the closest pair differs by 173 years.  Both schemes predict they are the same age.  No post-Flood depletion curve rescues this, because a depletion curve shifts all samples of the same true age by the same amount.

Reused stone.  Kitchen:  "Old-Kingdom decorated blocks with the names of several kings were reused in building Middle-Kingdom pyramid-temples, as at Lisht, in the structures of Amenemhat I (c. 1930 BC) (Goedicke 1971)."¹  A pyramid temple built out of quarried Old Kingdom monuments cannot be contemporary with the Old Kingdom.  Habermehl is the one creationist who meets this evidence, and she reads it the other way.  From Goedicke's catalogue, the source Kitchen cites, she concludes that Amenemhat I's "reign would have had to have extended at least into that of Pepi I, and possibly into that of Pepi II."¹⁸  That inverts the usual inference.  Quarrying a dead king's decorated blocks for fill shows his monument was already derelict, not that he was still reigning.  And the blocks carry several kings' names, so on her reading Amenemhat I would overlap most of the Old Kingdom at once.

The lunar chain.  Krauss and Warburton's Old Kingdom anchor is a lunar distance of at least 211 years between year 7 of Wenis in the late Fifth Dynasty and the Khozam date in the early Eleventh.⁵  Both schemes have to make that interval close to zero.

The same physical stratigraphy fixes the order within the Old Kingdom, and it has nothing to do with astronomy or Manetho.  Kitchen lists three facts.  On the Palermo Stone the Dynasty 1 and 2 kings are "clearly earlier" than those of Dynasties 3 to 6.  At Saqqara, "a mass of inscribed stone vessels of the Archaic Period rulers" was stacked in galleries under Djoser's Step Pyramid and "sealed off during the building work."  Also at Saqqara, "the late fifth Dynasty pyramid complex of Unas overlies tombs that contained sealings of Dynasty 2 kings, obliterating any superstructure of these tombs."¹  No creationist source read for this article discusses any of the three.

Courville also needs the Predynastic to vanish, and reads the Palermo Stone's first line as "alternate names for kings in the dark period at the end of Dynasty I."¹⁵  He never addresses the Predynastic cemeteries, which are treated in Part 6.

Where does the creationist side stand on route (a) now?  Patrick Clarke, the creationist writer with the strongest Egyptological training, judged the Velikovsky-derived schemes worthless in 2012.  He wrote:  "I discovered many problems with their attempt at synchronizing the Bible's historical time-line with that of ancient Egypt."²⁰  He promised a replacement over "a number of years."²⁰  Every paper he has published since is New Kingdom or later.  In 2022 CMI withdrew its endorsement of the popular alternatives:  "we have moved away from the positions laid out in earlier articles (particularly by David Down, and some by Patrick Clark)."¹²  That is a real credit to CMI.  It also means the detailed overlap schemes in print are Courville's and Habermehl's, and both fail on the same raw data.

Part 5: The radiocarbon-depletion route, tested

Route (b) says the Flood left the atmosphere short of carbon-14, so early post-Flood samples read too old.  Robert Carter's 2021 CMI treatment is the most careful statement of it.  His mechanism:  "If ancient samples started out with less carbon-14 than we expect, they will appear to be older than they really are… This age inflation should also increase as you sample older and older objects. Thus, we might expect samples from ancient Egypt or Jericho to be inflated by a few centuries."³  His prediction for Egypt:  "The earliest events need to be brought forward in time, the middle dates need to be adjusted a little, and the latter dates do not need to change much at all. In fact, carbon dating is very accurate over the last 2,000 years."³  Calibration in general belongs to the radiocarbon article.

Carter's shape is roughly the shape the data show.  The two-clock gap does grow with age, from +20 years at Dynasty 18 to +178 at Aha.  That is a point in his favour.  The problem is amplitude, not sign.  His scheme needs 142 years at Djoser on the Masoretic plain sum, and 312 on Ussher's date.  The measured gap there is 68 years against the low chronology and negative against the high one.  His own description of the data, that "the carbon dates were consistently older than the dates derived from archaeology,"³ is right in direction and wrong in size.

Then comes the admission, made twice.  "Currently, a biblical recalibration curve for carbon dates does not exist so we can only talk in generalities."³  And in his conclusion:  "Carbon dating is still a challenge to biblical archaeology and a biblical recalibration curve is desperately needed."³  Without a curve there is no prediction to test.  Carter says so himself, and that is to his credit.

Route (b) cannot move the historical clock.  Libby's first dates, as Carter records, put Djoser's and Sneferu's sarcophagus lids at "2,800 BC ± 250 years."³  Egyptologists had already put Djoser at about 2600 BC before Libby, from king lists alone.  Correct every radiocarbon date to zero and Djoser stays where the historical clock put him.

The best-known creationist radiocarbon quotation runs backwards.  Mitchell quotes the Cambridge Encyclopedia of Archaeology:  radiocarbon dates before the mid-first millennium BC "appear too recent, by up to several hundred years, by comparison with historical dates. Dates for the earliest comparative material available, reeds used as bonding between mud brick courses of tombs of Egyptians Dynasty I, about 3,100 B.C., appeared to be as much as 600 years, or about 12% too young."⁴  She concludes that "carbon dating is consistent with a much younger Egyptian civilization than traditional chronology claims."⁴  A raw radiocarbon age too young against a known calendar date is the textbook description of an uncalibrated result.  Atmospheric carbon-14 was higher in the third and fourth millennia BC, so raw radiocarbon years undercount calendar years there, and the tree-ring correction exists to fix that.  Once calibrated, the same First Dynasty material gives 3111–3045 BC for Aha.  Mitchell has taken the pre-calibration state of the field as a live result and drawn the opposite conclusion from it.

Part 6: The Septuagint escape and the Predynastic

Everything above assumes a Masoretic Flood date.  On the Septuagint's plain sum the Flood is about 3298 BC.  Djoser at 2676–2643 BC is then six centuries post-Flood, and Aha at 3111–3045 BC about two centuries.  No dynasty overlaps, no radiocarbon correction, no revision to Egyptology at all.  The whole pyramid problem dissolves.

This is the strongest move available to a creationist, and one creationist has already made it.  Anne Habermehl argued for the Septuagint at the 2013 International Conference on Creationism, by this article's own route.  Her abstract:  "It is shown that more time for events between the Flood and Abraham is needed than the Masoretic timeline allows; the longer chronology of the Septuagint is therefore most likely correct."¹¹  Her reason is the Predynastic, not the pyramids.  On the Masoretic timeline, she writes, "There simply isn't enough time for a 700-yr. Ice Age, repopulation along the Nile (Neolithic era), and development of Predynastic society."¹¹  She puts the Septuagint Flood at 3200 to 3100 BC.¹¹  Ten years later she set the question aside:  "the Septuagint versus Masoretic versions of the Bible do not come into this timeline discussion, because the differences in the length of their respective genealogies only come into play before Abraham's grandfather, Nahor, Terah's father."¹⁹  That is a retreat from her own 2013 argument, and the 2023 paper does not say why.  Mitchell and Bates do not raise the option.  The reader who asked CMI the question in 2020 named it himself:  "One could use Samaritan/Greek values in Gen 11 or gaps in Ex 6's genealogy, but our understanding of Egypt is likelier amiss than the received version of God's word."²  CMI's reply did not take it up.

Down and Ashton are the ones who argued against it, at p. 199 of Unwrapping the Pharaohs.  They describe "scholars" who try "to move the date of the Flood back beyond the biblical date of about 2,300 B.C." because "the LXX adds 100 years to most of the progenitors named in Genesis 5 and 11,"¹⁰ and give three reasons for refusing.  Motive:  "I can see why the Greek scribes could want to extend the periods. They were living in the Greek world, which believed in an older earth."¹⁰  Methuselah, who on the Septuagint's common numbers "died 14 years after the Flood, but only eight people survived the Flood in the ark, and Methuselah was not one of them."¹⁰  And "other instances of bad arithmetic in the LXX."¹⁰  Those are textual arguments, and they belong to the sibling article on the text-forms, which also treats the Septuagint variant of 167 for Methuselah that answers the second.  Down and Ashton priced the escape honestly and declined to pay.  The price is textual, not Egyptological.

Now the hard part.  The Septuagint rescues the pyramids and the First Dynasty, not what came before them.  Dee and colleagues, in 2013, ran 186 radiocarbon dates on Predynastic and First Dynasty material through ten Bayesian models.  Their 74 new measurements "prioritized short-lived remains such as seeds from granaries, reeds from basketry and fragments of linen."  The other 112 came from earlier literature, and 63 of those were on wood, charcoal or shell.⁸  That is a real weakness, and it runs the wrong way for this article:  wood can be centuries older than the context it sits in.  Their Table 1, at 68%:

The paper's own result was a compression.  "Our date for the conclusion of the Badarian culture centres on the thirty-eighth century BCE, some 200–300 years later than previously thought."⁸  And:  "our data support a shortening of the Egyptian Predynastic, the period over which state formation occurred, to between 600 and 700 calendar years."⁸  That is the direction a creationist wants, and it is nowhere near enough.  The Badarian farmers sit 1,100 years before the Septuagint Flood and 1,900 before Ussher's.

These are not king lists.  The Badarian and Naqada cemeteries are stratified and seriated on hundreds of graves.  No Manetho stands between the reader and them.  No creationist has published a chronology of the Predynastic.  Habermehl's 2013 paper is the nearest approach:  it takes the Predynastic to be real, to need centuries, and to break the Masoretic timeline.  It does not date it.  CMI's only statement is a sentence in a 2022 reply:  "Regarding where we would place the Naqada culture is difficult to say, but probably around the time of Babel, some 2,100 years BC, which is probably a pre-Dynastic date, but certainly not pre-Flood as the secular date suggests."¹²  CMI also quotes conventional dates from about 1800 BC down without qualification.  So on CMI's own figures, Badarian through the Eleventh Dynasty, conventionally about 4400 to 1980 BC, must fit between about 2450 and 1800 BC.  That is a compression of roughly 3.7 to 1, and the stated basis for it is that radiocarbon "is more unreliable the further one goes back in history."¹²

Part 7: The creationist literature audited

Here is what checking the creationist sources against their own citations found.

Mitchell (Answers in Genesis, 2010).  Three failures, all above:  the 2188 BC founding date rests on a twelfth-century Byzantine poet;  the radiocarbon quotation describes uncalibrated results and is footnoted not to the encyclopedia it comes from but to a creationist newsletter, Diggings⁴;  and the whole chronological argument is Manetho plus Sothis, neither of which carries the Old Kingdom.  Her chart's 3150 BC for Zoser's pyramid is footnoted to Will Durant's 1954 popular history.⁴

Bates (CMI, 2014, updated 2024).  Three checkable errors, all in the direction that helps the argument.  First:  "the first Egyptian dynasty is now conventionally believed to have begun under King Narmer (Menes in Greek) or Aha, or both contemporaneously, around 3400 BC."¹³  No current authority says 3400.  Dee gives 3111–3045, Kitchen 3000, the handbook about 2950.  The 3400 figure appears in Dee's paper as one of the superseded estimates the radiocarbon was tested against.⁸  Bates has taken the highest number in the field and called it the consensus, which inflates the gap he criticises by 300 to 450 years.  Second:  "the new ¹⁴C has now reduced the Old Kingdom beginnings by c. 400 years."¹³  The 400-year reduction applies to the start of the Predynastic, the Badarian, not the Old Kingdom.  Radiocarbon has moved the Old Kingdom the other way, about a century older than the handbook.  Third:  "there are six mentions of the rising of Sothis in Egyptian texts, none of them mention the name of any pharaoh whose reign they supposedly occurred in."¹³  False for the Ebers calendar.  Krauss:  "According to line 1 the calendar refers to regnal year 9 of King Amenhotep I."⁵

Habermehl (Answers Research Journal, 2023).  The most careful creationist synchronisation in print.  It lists seven crossover points, states the divergence at each, and names its own weak spot:  "how we can possibly fit about 800 secular years into about 300 biblical years."¹⁹  Its method is stated without disguise:  "We will therefore hold firmly to the biblical timeline, and will do whatever is necessary to force the (unreliable) standard timeline of Egypt to fit the biblical one."¹⁹  And it never dates the Flood.  Her "historical times" begin with Terah, "born 2126 B.C. on the biblical timeline (Jones 1993, 278) or about 3500 B.C. on the standard timeline."¹⁹  On the Ussher chronology she uses, the Flood is 222 years before Terah, so on her own conversion it falls well before 3500 BC standard, in the middle of the Naqada sequence.  The paper never says this.  Her two 2013 conference papers are stronger on the point that matters here.  They date the Flood on both texts, and they conclude that the Masoretic timeline cannot hold the Predynastic.¹¹  The 2023 paper drops that conclusion without arguing against it.

Cox and Bates (CMI, 2020 and 2022).  The honest statements.  "Based upon the information currently available, we don't think it is even possible to be definitive about this."²  Their caption states the problem exactly as this article does:  the Step Pyramid, "conventionally dated at 2670–2650 BC, placing it 300 years before Noah's Flood, which is clearly impossible."²  They gesture at a third route, that "during those first dynasties there are very scant archaeological remains, which points to small and hurried beginnings,"² and refer to a population-growth model in CMI's Tour Egypt booklet.  That booklet was not obtained, and the model is the only quantitative creationist contribution in this area.

What the critique gets right is collected in the Verdict.  One item belongs here, because it is the creationist side's best mainstream quotation:  Zahi Hawass, in press coverage of the 2010 Science paper, said "carbon dating is useless."¹³  He was objecting to radiocarbon overriding the historical chronology.  The 2025 study answered him by measurement, and the measurement went older.

Objections and responses

"Egyptologists themselves say the early chronology is uncertain by centuries."  They do, and the numbers are above.  Kitchen: over 200 years at the Archaic period, and Menes at 3100, 3000 or 2900 BC.  The handbook: no coherent contemporary chronology for Dynasties 1 to 3.  That band is real, and it is the whole of what the creationist gets.  Its floor, 2900 BC, is 380 years before the Masoretic plain-sum Flood and 550 before Ussher's.

"The mainstream is still fighting over Thera by a century, so nothing is settled."  The Thera dispute is the largest live disagreement in Egyptian chronology, and it is about one century in the seventeenth and sixteenth centuries BC, a thousand years after the Old Kingdom.²¹  Both sides of it are more than 900 years from any Masoretic Flood date.

"The 2025 paper proved the handbook was a century wrong.  Why trust it now?"  Because the error ran the wrong way.  Erdil's models "act to reaffirm the High chronological estimates achieved previously" and the handbook's low position "is ruled out."⁷  Every physical revision of the last fifteen years has made early Egypt older.

"Radiocarbon is circular:  the Bayesian models feed in the king lists."  The models do use reign lengths as priors, and Erdil concedes it:  "any major revisions to these sources of prior information would lead to alternative conclusions."⁷  Bronk Ramsey tested for it.  Doubling the uncertainty on every reign length left "the overall pattern... not altered."  Swapping in the handbook's rival reign lengths made "a more substantial difference," and still left the Old Kingdom "earlier than Hornung et al suggest."⁶  The calendar axis comes from tree rings, and Part 4's test uses uncalibrated values with no model at all.

"Pyramid mortar dated centuries too old, so Egyptian radiocarbon is unreliable."  True, and it ran too old.  Kitchen rejected Haas' mortar dates because they produced "a chronology nearly four centuries older than that commonly accepted."¹  Old wood and reused fuel in mortar inflate ages, which is why the 2010 and 2025 studies used seeds, reeds and linen.  A creationist who cites Egyptologists' distrust of radiocarbon is citing distrust of dates that were too old, not too young.

"A post-Flood carbon-14 deficit explains the radiocarbon."  To reach Ussher's date it would have to explain 312 years at Djoser and 730 at Aha, while the measured gap between the two clocks is 68 and 178.  And it would leave the historical clock untouched.  Carter, who holds this position, says no curve exists, so there is nothing to test.

"Manetho's dynasties overlapped, and even Egyptologists admit it."  For the Third Intermediate Period and the Thirteenth Dynasty, yes.  For the Old Kingdom the detailed proposals are Courville's and Habermehl's, and both fail on raw radiocarbon, on reused blocks at Lisht, and on the lunar chain.  The overlap licence itself comes from Eusebius, and it begins "But if the number of years is still in excess."

"The stone vessels under the Step Pyramid could have been collected in a few years."  Perhaps.  The point is order, not duration:  Archaic kings' vessels sealed under a Third Dynasty monument, and a Fifth Dynasty complex built over Second Dynasty tombs.

"Then take the Septuagint and the problem is gone."  For the pyramids and the First Dynasty, yes.  For the Badarian and Naqada cemeteries, no.  They sit 1,100 years before the Septuagint Flood.  A creationist who takes the Septuagint gains the pyramids and still owes an account of Naqada.

Objections to this article's own verdict.

"The historical clock is not independent of radiocarbon; Egyptologists adjusted their dates to fit it."  Erdil 2025 is the test.  The handbook's 2006 dates were set without the 2010 radiocarbon, and radiocarbon then ruled them out at 95%.  Two clocks being tuned to each other would not do that.

"The two-clock gap is inside the error bars, so it proves nothing."  Correct, and that is the finding.  Two independent methods agreeing inside their stated errors across more than 1,500 years is evidence that both are roughly right.  To be wrong by 250 to 600 years, they would have to be wrong by the same amount for different reasons.

"You have not read Bronk Ramsey 2010's body."  True;  the running text is paywalled.  Its supporting material is free and prints the modelled date for every king, and that is where the figures used here come from.

Issues and unanswered questions

Where the creationist side has no published answer.  The Predynastic cemeteries.  The stratigraphy under Djoser's pyramid and over the Second Dynasty tombs.  The Erdil 2025 raw dates.  A recalibration curve for route (b).  And the joint requirement of Part 3:  why two independent clocks would agree if both were wrong.

Computations that would settle what is still open.

1. Test whether any monotone correction curve compresses the Predynastic. Dee 2013's supplementary Table S1 lists 186 individual dates and is free at the Royal Society. The question is whether a single correction function can map all of them into a 250-year window while leaving the Twelfth Dynasty within 50 years of its historical position. two-clock-test.ts sets up the frame; Table S1 has not been downloaded.
2. Quantify the pyramid-mortar offset. Bonani and colleagues' 2001 paper reports over 450 samples from Old and Middle Kingdom monuments and would say exactly how far mortar inclusions run old.²² The whole paper is on disk, but its two date-list appendices, pp. 1302 to 1320, are page images with no text layer. They need optical character recognition before the sample-by-sample figures can be used.
3. Check CMI's population model. The Tour Egypt booklet reportedly models post-Babel growth. Whether it produces the workforce for Giza within a century or two of eight survivors, and accounts for the Predynastic burials, has not been checked.

Where this article's own case is weakest.  The Early Dynastic year-count really is conjectural, and the article leans on Dee 2013's radiocarbon to fill it.  That paper's own authors moved the Badarian by 200–300 years in one revision, and the handbook editors say radiocarbon at the Predynastic junction "can only offer a limited degree of precision."⁵  The two-clock test carries the full uncertainty of both inputs.  Down and Ashton's Numbers 1 and 26 arithmetic examples were not checked against a Greek text.  Goedicke's catalogue of the reused Lisht blocks was not read, so Habermehl's reading of them is answered from Kitchen's summary rather than from the blocks.  And the article has not read the excavation reports behind Kitchen's three stratigraphic facts.

Verdict

A Flood on any Masoretic date cannot be reconciled with the Egyptian record, and the popular creationist attempts fail on their own citations.  The Old Kingdom is not Sothically dated, so the Sothic critique moves it zero years.  The king lists and the atoms agree to within 178 years across more than 1,500 years.  Landing Djoser after Ussher's Flood needs both to be wrong by 244 and 312 years for unrelated reasons.  The two detailed overlap schemes are refuted by uncalibrated radiocarbon and by reused stone.  The one detailed depletion scheme has, by its author's admission, no curve.  Every creationist founding date for Egypt comes from a Christian chronographer of the fourth or twelfth century AD.

What the young-earth side gets right is not nothing.  Kitchen's 200-year band at Dynasty 1 is real.  The Annals sum is conjectural.  The Turin Canon's archaic names are corrupt.  Manetho's Thirteenth Dynasty total is absurd, and parallel dynasties are real where Egyptologists run them.  Mortar radiocarbon does run old.  The handbook's Old Kingdom dates were about a century off as recently as 2006.  None of that reaches 600 years.

What an honest young-earth position looks like.  Follow Hardy and Carter rather than Ussher.  Say the Flood date spans 1,300 years on textual grounds, and that the top of the range, the Septuagint's about 3300 BC, clears Djoser and Aha on the mainstream chronology without moving one Egyptian date.  Pay the textual price Down and Ashton named, or explain why it need not be paid.  Habermehl published that position in 2013 and nobody followed her, including herself.  Then say plainly, as Cox and Bates already have, that no account of the Predynastic exists.  The pyramids are not the problem.  The farmers before them are.
