How Old Does the Bible Say Earth Is?

We have to distinguish between literal intention and historical, factual truth.  The figures are not, to us, historically, scientifically or factually true, but they were literally intended.¹

Accounting for all presently known relevant details and assuming the Babylonian Captivity began in 587 or 586 BC, we can say with confidence that the Bible places limits on the year of creation between 5665 and 3822 BC.²

The extent of the presently available long dendrochronologies argues forcefully for a Flood date in excess of 10,000 years ago.³

Summary

The Bible never states the age of the earth.  It gives a chain of numbers from which an age can be added up, and the sum is what everyone argues about.  This article does three things.  It shows where the sum comes from and what it assumes.  It separates the two claims the sum carries, the age of humanity and the age of the earth, and shows that the text holds one of them more tightly than the other.  And it builds a falsification table:  for each of the three readings a Bible-believing reader can take, it lists the observations that would refute the reading, says whether those observations have been made, points to this site's own reply, and rates the reply.  The dating articles on this site do the physical work;  this page does not repeat it.

1. No verse gives an age.  The date of creation is a sum of five links, and only the last one touches a calendar.  Genesis 5 and 11 give each patriarch's age at the birth of the next, from Adam to Abraham.  Genesis 21:5, 25:26 and 47:9 carry the line to Jacob's entry into Egypt.  Exodus 12:40 gives 430 years in Egypt.  1 Kings 6:1 gives 480 years from the Exodus to Solomon's fourth year.  The kings of Judah and Israel then run down to an Assyrian eclipse dated to 15 June 763 BC, the one point in the whole chain that is fixed by astronomy.^{4 2}  Chris Hardy and Robert Carter, two young-earth researchers writing in Journal of Creation, worked every link with its uncertainty and put creation between 5665 and 3822 BC.²

2. The three surviving text-forms of Genesis put creation between about 4,200 and 5,600 BC and the Flood between about 2,500 and 3,300 BC.  On a 2166 BC birth of Abraham the Masoretic Text gives creation in 4174 BC and the Flood in 2518 BC;  the Samaritan Pentateuch 4415 and 3108;  the Septuagint 5560 and 3298.  Babel follows the Flood by 101 years on the Hebrew numbers and 531 on the Greek.⁵  The text-forms article argues which set is original;  this article takes its numbers and notes only that the whole spread is 1,386 years.

3. The date of humanity is the firmer of the two claims, because it rests on the genealogies alone.  Adam's date needs only Genesis 5 and 11 read as the chronology they present themselves as.  The earth's date needs one more step:  that "in the beginning" (Gen 1:1) sits inside the first day.  Three readings sever it.  The gap theory puts ages between verses 1 and 2;  John Sailhamer reads reshit (רֵאשִׁית) as an age of unstated length;  John Lennox spaces the days apart.⁶  The obstacle to all three is Exodus 20:11, which says that "in six days the Lord made the heavens and the earth and the sea and all that is in them."⁴  The grammar article and the competing-readings article score that obstacle;  here the point is only that the earth's age can be loosened by one exegetical move and humanity's cannot.

4. The sum rests on five named assumptions, and their combined reach is about 1,900 years.  Which text-form carries the numbers (1,386 years).  Whether Israel was in Egypt 430 years or 215 (215 years).  Whether Abram was born in Terah's 70th year or his 130th (60 years).  Whether 1 Kings 6:1 reads 480 or 440, or is discarded for a thirteenth-century Exodus (40 to about 180 years).  How the reigns of the kings are synchronised (about 54 years).^{2 5 7}  Stack every choice toward age and creation still lands before 5,700 BC.  No reading of the numbers reaches 6,000 BC.

5. Gaps in the genealogies add names, not years, so they cannot stretch the sum.  Every verse in Genesis 5 and 11 dates the birth of the son it names, whatever generations lie between.  William Henry Green proved in 1890 that biblical genealogies skip names;  he did not show that these two skip years, and his one clause to that effect was never argued.⁸  James Barr, Regius Professor of Hebrew at Oxford and no friend of creationism, put the crux in 1987:  the figures "were literally intended," and calling them non-literal is "a cowardly expedient."¹

6. The falsification table below is this article's own contribution.  For the young-earth reading it lists ten observations that would refute a creation after about 5,600 BC or a Flood after about 3,300 BC.  Nine of the ten have been made and published.  For each, the table names the young-earth reply on this site and rates it.  Two are partly answered, both by the Greek chronology, and seven are unanswered by this site's own account.

7. The decisive row is a tree-ring count, and a young-earth researcher said so in 1993.  The Hohenheim oak and pine chronology runs, ring by counted ring, to 10,461 BC.⁹  The IntCal20 radiocarbon calibration rests on "securely dated tree-ring data" for the last 12,310 years.¹⁰  Gerald Aardsma of the Institute for Creation Research tested the multiple-rings-per-year escape against the radiocarbon wiggles, found it failed, and wrote that the Flood "must, in fact, have occurred more than 10,000 years ago."³  Every radiocarbon row in the table depends on this one, because the calibration is anchored to the rings.

8. The old-earth, young-humanity reading passes the rock tests and fails every human one.  Göbekli Tepe's Enclosure D is dated by wall plaster and charcoal to 9745 to 9311 cal BC.¹¹  Çatalhöyük was occupied from about 7100 to 5865 cal BC and records the 8.2 ka climate event inside its building sequence.^{12 13 14}  The Egyptian state was founded in 3111 to 3045 BC on 186 radiocarbon dates.¹⁵  Human genetic diversity puts the most recent possible single-couple origin at 100,000 to 500,000 years.^{16 17}  None of these is a rock date.  A reader who keeps the genealogies and drops the young earth inherits all of them and gains nothing.

9. The old-earth, old-humanity reading passes the physical tests by conceding the textual ones.  William Lane Craig places Adam "more than 750,000 years ago" as Homo heidelbergensis.¹⁸  That reading must say the Genesis 5 and 11 numbers are not a chronology, and it must read Genesis 4 as something other than history:  seven generations from Adam, Tubal-Cain "heated metal and shaped all kinds of tools made of bronze and iron" (Gen 4:22), a technology that on the conventional chronology begins "a little after 2000 BC."^{4 19}  It must also read "from the beginning of creation" (Mark 10:6) as the beginning of the human story rather than of the world.²⁰

10. Which doctrine hangs on which number is stated in the last section.  The Sabbath command rests on the six days.  Paul's argument in Romans 5 needs a first man but gives him no date.  Death before the Fall is a question about the age of the fossils, which is the age of the earth.  The church-history article and the Adam article carry the arguments;  this page sorts them by which number they depend on.^{20 21}

Verdict:  The Bible's numbers put humanity under about 7,600 years old on the longest text-form and under about 6,200 on the shortest, and they put the earth at the same age unless Genesis 1:1 is severed from the six days.  The earth's age is the more negotiable of the two claims textually, because one exegetical move loosens it, and the less negotiable one physically, because the counted and radiometric clocks that contradict it are the ones this site has not answered.  The falsification table shows where the young-earth reading stands:  it survives the written record and the sequence of human technology, and it has no answer on this site to the tree rings, the ice, the radiocarbon-dated Neolithic, or the human genome.

No verse gives an age; five links do

Ask the Bible how old the earth is and it does not answer.  There is no verse that says "the world was made so many years ago."  What the Bible gives is a chain of numbers that can be added, and every writer who has ever dated creation from Scripture, from Josephus to Ussher to the Journal of Creation, has added the same chain.²⁰  Its five links are these.

Only the fifth link touches a calendar.  The Assyrian eponym list records a solar eclipse in the year of Bur-Sagale, which astronomy fixes to 15 June 763 BC;  Thiele's reconstruction of the Hebrew kings runs from that eclipse to 931 BC for the division of the kingdom and 966 or 967 BC for Solomon's fourth year.⁷  Everything earlier is Scripture's own arithmetic laid on that one date.  So 966 BC plus 480 puts the Exodus at 1446 BC;  plus 430 puts Jacob's entry into Egypt at 1876;  plus 290 puts Abraham's birth at 2166;  and Genesis 5 and 11 carry the line back from there.^{4 5}

Hardy and Carter did this in 2014 with every uncertainty carried through, including rounding conventions, a possible one-based birthday count, and lunar years before the Exodus.  Their abstract is worth quoting because it is the young-earth side stating its own error bars:

Implied precision and potential cultural differences (e.g. calendar systems, birthday conventions, and rounding conventions) mean we cannot pinpoint the age of the earth to a single year, yet the accumulated imprecision from those sources is limited to a maximum range of 308 years.  Even including textual variants and debates over interpretation does not allow for dates approaching 10,000, let alone billions of years of Earth history.²

Their final table puts creation between 3822 BC (Masoretic, short sojourn, lunar years) and 5665 BC (Septuagint, long sojourn, maximum rounding), and the Flood "certainly between 3386 BC and 2256 BC."²  They add a line that cuts against their own camp:  the only way to reach the traditional 4000 BC is the short sojourn with minimal adjustments, which "makes it likely that the earth is several hundred years older than most biblical creationists expect."²

The three text-forms give creation between 4,200 and 5,600 BC

The first link is the one that matters, because it carries the whole disagreement.  The Hebrew Masoretic Text, the Greek Septuagint and the Samaritan Pentateuch give different begetting ages in Genesis 5 and 11, and the Greek adds a second Cainan in Genesis 11.  The text-forms article argues out which is original and comes down, at about 70% confidence, for the Hebrew.  Its verified dates on a 2166 BC birth of Abraham are these.⁵

Three things about that table.  The Masoretic and Septuagint rows take Abram's birth in Terah's 130th year, which Acts 7:4 forces if Terah lived 205 years;  the Samaritan row takes his 70th, because the Samaritan gives Terah 145 and its numbers cohere only that way.⁵  Ussher's 4004 BC is the Masoretic row moved to a 1996 BC anchor for Abraham, and the arithmetic reproduces his 4004, 2348 and 2247 exactly.⁵  And Jonathan Sarfati, writing for Creation Ministries International in 2003, gives the same bound from the other direction:  the Septuagint and Samaritan "at most could only stretch this date out to about 5400 BC."²²

Babel is not dated by any verse.  Genesis 10:25 says the earth was divided in Peleg's days, so the usual practice puts Babel between Peleg's birth and his death, which on the Hebrew numbers is 101 to 340 years after the Flood.  This article uses Peleg's birth as the earliest bound and does not lean on it.

The assumptions, and how far each can move the date

A skeptic is entitled to ask what the sum assumes.  The honest list has six items.  The first five are choices between readings the manuscripts actually carry;  the sixth is a reading nobody's manuscript carries.

Take the first five at their most generous, all in the direction of age, and creation lands at 5665 BC on Hardy and Carter's arithmetic, or 5560 BC on this site's Septuagint figures.^{2 5}  Take them at their least generous and it lands at 3822 BC.  The whole range is under 2,000 years, and none of it reaches 6,000 BC.  That is why the sixth row exists.  Since William Henry Green's 1890 article, the standard escape has been that the genealogies skip generations and therefore skip years.  The genealogies article traces the argument to its source and finds that it proves the first half and not the second.  Green showed that Matthew 1 and Ezra 7 skip names, and that Exodus 6 must.  He did not show that "when Enosh had lived 90 years, he became the father of Kenan" (Gen 5:9) dates anything but Kenan's birth, and his single clause allowing that reading was never argued and has no parallel in the language.⁸  A missing name changes the family tree.  It does not move a date that the verse states.

The most generous reading that keeps the numbers, Frederic Gardiner's 1873 proposal that each begetting age dates a firstborn rather than the named son, adds at most about 8,700 years and is refuted by Genesis 5:7, which counts Seth's remaining 807 years from Enosh's birth.⁸  Even that ceiling, about 12,800 BC, is not the 200,000 years an old humanity needs.

Barr's verdict is the one to keep.  The numbers "were literally intended:  they were chronological statements of numbers of years and made no sense otherwise."¹  A reader who wants an old humanity has to say they are wrong.  Saying they have gaps does not get there.

The earth's date can be loosened in the text; humanity's cannot

The sum above dates Adam.  It dates the earth only if the earth was made in the same week as Adam, and that is a separate claim resting on a separate set of verses.

What ties the earth to the week is Genesis 1:1 read as the first act of day one, and Exodus 20:11 read as a statement of duration:  "For in six days the Lord made the heavens and the earth and the sea and all that is in them, and he rested on the seventh day."⁴  If "the heavens and the earth" of Genesis 1:1 were made inside the six days, the earth is as old as Adam plus five days.

Three readings sever the tie, and the competing-readings article scores each of them against the text.⁶  The gap theory, from Thomas Chalmers in 1814 through the Scofield Bible, puts an unstated age between verse 1 and verse 2, with the earth "becoming" formless after a ruin.  It fails on the grammar of hayetah (הָיְתָה), which is a plain "was," and on the fact that verse 2 is a circumstantial clause describing the earth as created, not as ruined.  Sailhamer's Genesis Unbound reads reshit (רֵאשִׁית), "beginning," as a period of unstated length, so that the universe and the earth are made in verse 1 and the six days prepare the promised land;  Andrew Kulikovsky's review showed that his two proof texts for a durative "beginning" do not carry the sense.  Lennox keeps the days as ordinary days and spaces them apart by ages, a reading J. Barton Payne traced to 1904 and conceded came from science rather than the text.

Each of these readings pays a textual price, and the sibling article states the price.  But note what they have in common.  Every one of them keeps Adam on day six and keeps the genealogies as they are.  The gap theory's own advocates, from Chalmers to Custance, held a recent Adam.  Sailhamer's promised-land week ends with a historical Adam a few thousand years ago.  Lennox's spaced days still produce a man on the last of them.  So the earth's age can be moved by an exegetical decision about one verse, while the age of humanity is held by twenty verses in two chapters that each state a number.

That asymmetry is the shape of the whole question.  Textually, the earth's age is the softer claim.  Physically, as the next section shows, it is the harder one, because the clocks that contradict it are the ones this site has examined and not answered.

The falsification table

A claim that can be checked can be refuted.  The Bible's numbers are checkable, so it is fair to ask, for each way of reading them, what observation would show the reading false, and whether that observation has been made.  That is what the three tables below do.  Each row names an observation, says whether it has been made, points to this site's own treatment, and gives a rating.

The ratings mean this.  Passes means the observation has not been made, or the reading survives it.  Partly answered means one of the readings' own variants meets the observation and another does not.  Unanswered means the observation has been made and the reply on this site does not, by its own account, meet it.  Unaudited means the observation is claimed in the literature and this site has not yet examined it.  A skeptic should notice that no row is rated "answered."  That is not modesty.  It is what the dating articles on this site found when they did the work.

Reading 1: young earth and young humanity

The reading:  creation no earlier than about 5,600 BC, the Flood no earlier than about 3,300 BC, Adam made in the same week as the earth.  This is the reading of the site.  What would refute it is any human, biological or geological record that runs continuously through those dates.

Two further observations belong beside the table rather than in it, because they are predictions the reading makes rather than refutations it faces.  The reading predicts pre-Flood human remains somewhere in the Flood strata;  none have been found, and the Institute for Creation Research says so.²⁹  And it puts bronze and iron tools seven generations from Adam (Gen 4:22), which on the Hebrew numbers is centuries before the Flood, while the archaeological record shows smelted iron "beginning a little after 2000 BC" and none before the second millennium.¹⁹  A pre-Flood metallurgy that left no trace is not impossible.  It is unevidenced.

Reading 2: old earth and young humanity

The reading:  the gap theory, Sailhamer's promised-land week, Lennox's spaced days, or any other reading that lets the earth be old and keeps the genealogies.  Adam no earlier than about 5,600 BC;  the Flood no earlier than about 3,300 BC.  What would refute it is any human or biological record older than Adam, and any record running through the Flood.  The rock rows disappear.  Every human row stays.

This is the reading that gains least.  It pays the textual price of severing Genesis 1:1 from the week, which the competing-readings article prices, and in return it escapes only the rows that never mentioned a human.  Every observation about people, from Göbekli Tepe to the genome, hits it as hard as it hits the young-earth reading, and the Flood rows hit it identically.  A reader who takes this reading because the rocks look old has bought relief from the rocks and none from the archaeology.

Reading 3: old earth and old humanity

The reading:  Adam a real man, but placed by science rather than by the genealogies.  William Lane Craig identifies him with Homo heidelbergensis, "living more than 750,000 years ago."¹⁸  Joshua Swamidass's genealogical Adam is a variant:  a couple created about 6,000 years ago whose descendants interbred with a humanity that evolved outside the garden.²¹  Denis Lamoureux's evolutionary creation drops Adam altogether.  What would refute Craig's reading is not a physical observation.  It is the text.

The pattern is the mirror of reading 1.  Where the young-earth reading passes the text and fails the clocks, this reading passes the clocks and fails the text, and it fails the text in more places than the numbers.  Genesis 4 is the row that is usually forgotten.  Whoever moves Adam to the Middle Pleistocene has to move Cain's city, Jabal's tents, Jubal's flute and Tubal-Cain's iron with him, or declare the chapter a story.

What the tables show

Three things.

First, the young-earth reading is falsifiable and has been tested.  Nine of its ten refuting observations have been made.  That is not a reason to abandon it before the replies are heard, and the replies are on this site.  It is a reason to say plainly that the reading is carrying an evidential debt, and where.

Second, the debt is not where the popular argument puts it.  The public case against a young earth is radiometric, and the young-earth reply to radiometric dating, accelerated decay, at least names a mechanism.  The rows this site cannot answer are the counted ones:  rings, ice, laminae, and the radiocarbon that rides on the rings.  Those need no decay constant.  They need someone to have counted wrong, by a factor of two in the Holocene alone, in three independent archives that agree with each other.  Gerald Aardsma was the first young-earth researcher to run that test quantitatively, and he printed the result in 1993:  the Flood "must, in fact, have occurred more than 10,000 years ago."³  No one on the young-earth side has overturned his measurement.  The current proposals, Woodmorappe's disturbance-bundles and Jordan's 2026 simulation, make a radiocarbon prediction their authors have not tested.³⁰

Third, the humanity date is where all three readings converge on the same evidence.  Göbekli Tepe, Çatalhöyük, the Badarian villages and the human genome are not rock dates.  They are the record of people, and they run four to six thousand years past any date the genealogies allow.  A reader who wants to keep the genealogies has to answer them, whatever he thinks about the rocks.  A reader who lets the genealogies go has to say what he is keeping.

Which doctrines hang on which number

The church-history article lists the doctrines that depend on chronology and gives both sides of each.  This section sorts them by which of the two numbers they need.

Doctrines that hang on the earth's age, that is, on Genesis 1:1 being inside the week.  The Sabbath command:  "in six days the Lord made the heavens and the earth and the sea and all that is in them" (Exod 20:11).⁴  If the earth is old, the verse is a pattern and not a duration, which is what Kline and Ross both say and what the grammar article finds hard to hold.  Death before the Fall:  if the fossils are older than Adam, every predator, tumour and thorn in them preceded sin, and the Adam article and its child on animal death state what that costs.  These two doctrines are the reason the earth's age matters to theology at all.  Neither is touched by the date of Adam.

Doctrines that hang on Adam being a person, with no date attached.  Paul's argument in Romans 5 and 1 Corinthians 15 needs a first man through whom death came.  Luke's genealogy ends at Adam.  Jude counts Enoch seventh from him.  Craig's reading keeps all of these at 750,000 years;  Swamidass's keeps them at 6,000 with a population outside the garden.  What neither can keep is Genesis 4 and 5 as history, and that is a question about the text, not about theology.

Doctrines that hang on the numbers themselves.  Only one, and it is inerrancy in the strict sense.  If the begetting ages are a chronology and the chronology is false, then Genesis states something false.  Barr thought it did and said so.  Green and Warfield thought the numbers were true but not a chronology, which the genealogies article finds the text does not allow.  Craig thinks they are mytho-history, which is a genre claim about a chapter that gives two numbers per verse.  There is no fourth option that keeps both the plain reading and an old humanity.

Doctrines that hang on neither number.  Creation from nothing, the goodness of the creation, the image of God, the historicity of the Flood as a judgment.  Each has been held by Christians who dated the earth at 6,000 years and by Christians who dated it at billions.  None of them is settled by the falsification table, and this article makes no claim that it is.

Common objections

Objection 1: "The Bible does not give an age, so young-earth creationism is an inference, not a doctrine."

Correct, and this article says so in its first sentence.  The age is a sum.  But the sum is not an inference in the sense the objection means.  Every number in it is stated in the text, the text presents Genesis 5 and 11 as a chronology, and the one link fixed by astronomy is an Assyrian eclipse rather than a theological premise.  An age derived by addition from twenty stated numbers is an inference the way the date of a birth is an inference from a birth certificate.

Objection 2: "A day with the Lord is as a thousand years. The Bible itself says the days are not literal."

Psalm 90:4 and 2 Peter 3:8 are similes about God's relation to time, and a simile needs its terms to keep their ordinary sense.  The grammar article works this through.  The point here is narrower.  Even if the days of Genesis 1 were ages, the genealogies would still date Adam to about 4,000 BC on the Hebrew numbers, so the objection loosens the earth's age and leaves humanity's where it was.

Objection 3: "The Septuagint solves the problem. Its extra 1,400 years clear Egypt."

They clear Egypt and nothing else.  The Greek Flood at 3298 BC falls after the founding of the Egyptian state and about 20 years after the first Egyptian writing, which is why rows 2 and 3 are rated partly answered.  Against Göbekli Tepe the same 1,400 years covers about a quarter of the gap, and the 780 extra years at the Flood cover about 11% of the gap from the Flood.  Against the tree rings, ice and genome it covers nothing.  The text-forms article also finds the Greek numbers the weaker text on internal grounds, so the relief is bought at a textual cost.

Objection 4: "Gaps in the genealogies can add as much time as needed."

They can add names.  They cannot add years, because each verse dates the birth of the son it names.  Green conceded the sum as a minimum;  Warfield conceded that the begetting ages "differentiated" these lists from every other genealogy in Scripture.⁸  The genealogies article computes the most generous ceiling any reading of the numbers allows, about 12,800 BC, and shows that even that fails on Genesis 5:7.

Objection 5: "Radiocarbon is calibrated against tree rings and tree rings against radiocarbon. The whole thing is circular."

The Hohenheim chronology is built by matching ring-width patterns between overlapping trees, with a mean of 108 trees in every year, and radiocarbon is measured on the rings afterwards.⁹  The crossdating does not use carbon.  Where a floating section was later joined to the master chronology by ring matching alone, its position agreed with the earlier radiocarbon wiggle-match to eight years, which is what independence looks like.  The circularity charge is answered in the tree-ring article, and by Aardsma, who used the rings and the carbon against each other to test the young-earth escape and found it failed.

Objection 6: "Falsification is a naive philosophy of science. Every model has anomalies."

It does, and this site's own dating articles list the anomalies on the other side:  the unexplained carbon-14 residue in coal, the Green River lamina counts, the 50% interpolation in the Suigetsu varves, the manual-counting bias the ice-core team admitted in 2015.  The tables above do not treat one unanswered row as a refutation.  They treat seven unanswered rows in independent archives that agree with each other as a debt, and they say so.  A reading that cannot say what would refute it is not a stronger reading.  It is a weaker one, and the front-loaded-genome reply in row 10 is the example.

Objection 7: "Why not take Sailhamer's reading and keep both the text and the rocks?"

Because the rocks were never the hard part.  Reading 2 shows what Sailhamer buys:  the radiometric row and the ice and lake rows, and not one of the human rows.  Göbekli Tepe is older than Sailhamer's Adam by four thousand years.  The Hohenheim oaks grew through Sailhamer's Flood.  A reader who takes that reading to make peace with geology has made peace with the wrong discipline.

Objection 8: "If the young-earth reading has seven unanswered rows, why does this site hold it?"

Because the question this article asks is what the text says, and the text says it.  The genre and grammar articles, the church-history article, and the hostile witnesses from Barr to Walton agree that the author meant a young world and a young humanity.  Whether he was right is a question for the clocks, and this article reports where the clocks stand rather than pretending they stand elsewhere.  A site that holds the reading owes its readers the ledger.  This is the ledger.
