Scripture gives no number. The famous 6,000 years is a seventeenth century calculation, and Christians of real faith read the days of Genesis in several different ways.
How old is the earth according to the Bible? The Bible does not say. No verse gives an age for the earth, and Genesis was not written to supply one.
The well known figure of about 6,000 years comes from adding up genealogies, most famously in Archbishop James Ussher's 1650 chronology. Geologists put the earth at about 4.54 billion years, and a Christian can accept that without giving up anything Genesis actually teaches.
That is our answer, and we will show our work. We will also be fair to brothers and sisters who land somewhere else, because Christians of good faith differ on this, and nobody's salvation hangs on a date.
The young earth number is not pulled from thin air. It comes from treating the genealogies of Genesis as a continuous clock and adding them up. Here is how the sum gets built.
Each entry gives a father's age when his son was born. Adam was 130 when Seth arrived, Seth was 105 when Enosh arrived, and so on. Add them in the Hebrew text and the flood lands 1,656 years after creation.
The same pattern runs after the flood, down to Terah and Abram. The Hebrew numbers add roughly another three centuries.
From there the counter stitches together the patriarchs, the years in Egypt, the judges and the reigns of the kings. Every joint involves a judgment call, which is why the totals vary.
The Archbishop of Armagh concluded, in the words of The Irish Times, that the world “had begun one weekend in 4004 BC”, on the evening before October 23. His dates were later printed in the margins of English Bibles, which is how many readers came to think the number was Scripture.
Add 4004 to the current year and you get just over 6,000. The Jewish calendar counts from creation by its own ancient reckoning, and it began year 5787 this September.
Ussher was no crank. In his day this was serious scholarship, and others ran the same sums with slightly different results. Bede landed on 3952 BC and Kepler on 3992 BC.
The 6,000 years is a calculation made from the Bible, not a statement in the Bible. A calculation is only as sound as its assumptions.
Here is something most people who quote the 6,000 years have never been told. The ages in Genesis 5 and 11 are not the same in every ancient copy of Genesis.
The basis of most English Bibles. Creation to the flood is 1,656 years, and the flood to Abraham is 292.
The Greek Old Testament, quoted again and again in the New. Creation to the flood is 2,242 or 2,262 years depending on the manuscript, and the flood to Abraham runs past a thousand.
Preserved by the Samaritan community. Creation to the flood is 1,307 years, and the flood to Abraham is 942.
Luke 3:36 names a Cainan between Arphaxad and Shelah. The Greek text of Genesis 11 has him. The Hebrew text does not.
Those figures come from Gerhard Hasel's study of Genesis 5 and 11, and to be fair, Hasel argued the Hebrew numbers are the originals. Even so, the Greek count puts creation well over a thousand years before Ussher's date, and much of the early church read that Greek Bible.
There is a second problem. Biblical genealogies are not always complete. Matthew 1:8 calls Joram the father of Uzziah, and 1 Chronicles 3:11 and 12 show three kings between them. Matthew was not making a mistake. “Father of” could mean ancestor of, and genealogies were shaped to make a point. Once you allow that, the clock stops working as a clock.
Which ancient text of Genesis gives the longest span from creation to Abraham?
The Septuagint adds well over a thousand years before Abraham compared with the Hebrew. Same book, same chapters, different numbers, which is why no single date can claim to be the biblical one.

Christians who love the Bible read Genesis 1 in several ways. Each one below is held by serious believers, and each deserves to be heard at its strongest. We start with the one that feels most obvious.
“For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.”
Exodus 20:11Six ordinary days, genealogies close to complete, an earth thousands of years old. Its case is real: numbered days with evening and morning read naturally as ordinary days, Exodus 20:11 ties the work week to the creation week, and Romans 5:12 says death entered through sin. Many devoted believers hold it because they want to take Scripture seriously.
The Hebrew word for day can mean a long period, so each day is an age. Supporters note that Genesis 2:4 uses “day” for the whole creation week, and that the seventh day never closes with evening and morning. This reading accepts the scientific age of the earth.
God made an original creation in Genesis 1:1, ages passed, and verse 2 describes a later ruin before the six days. Thomas Chalmers proposed it in 1814, and the Scofield Reference Bible of 1909 spread it widely. Fewer hold it today, since nothing in the text clearly signals an event between the two verses.
The days are a literary structure, not a stopwatch. Days one to three form the spaces: light, sky and sea, dry land. Days four to six fill them: sun and stars, birds and fish, animals and people. Meredith Kline developed this reading, summarized well by Lee Irons, and it explains why the sun appears on day four after light on day one.
John Walton argues that Genesis 1 describes God giving the cosmos its functions and taking up residence in it as his temple, which is why the week ends with God at rest. On this reading the chapter is not about material origins, so it says nothing about the earth's age.
Notice that only the first reading requires a young earth. The other four leave the date open, and none of them treats Genesis as a science textbook.
It is common to hear that Christians only started reading Genesis figuratively once science forced them to. The record says otherwise.
Around AD 225, Origen of Alexandria asked, “For who that has understanding will suppose that the first, and second, and third day, and the evening and the morning, existed without a sun, and moon, and stars?”
Two centuries later Augustine wrote of the creation days in The City of God, “What kind of days these were it is extremely difficult, or perhaps impossible for us to conceive, and how much more to say!” Neither man had seen a fossil or a rock layer. They were reading the text closely.
“God called the light Day.” Here yom is the daylight hours, not a full twenty four.
“The evening and the morning were the first day.” Here it is a whole numbered day.
“In the day that the LORD God made the earth and the heavens.” Here one yom covers the entire creation account.
The word stretches, and context decides. That is why careful readers land in different places.
Augustine also warned what happens when Christians get this wrong in public. In The Literal Meaning of Genesis he wrote that “it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking nonsense on these topics”. His worry was not the believer's pride. It was the people who would reject Scripture because of it.
So what do the rocks say? The U.S. Geological Survey gives the age of the earth and the solar system as “4.54 billion years with an uncertainty of less than 1 percent”, based on radioactive decay measured in ancient lead and in meteorites. That is careful measurement, not a plot against the Bible.
We read the six days of Genesis 1 as a literary frame, a carefully built week that tells us who made the world, why it is good and where people fit. We said the same when we asked what day God created man. A frame like that is true in what it teaches, and it was never meant to be a timer.
So we do not hold to a 6,000 year old earth, and we have no quarrel with the 4.54 billion year figure. Adding up genealogies to date creation asks the text a question it was not written to answer. That method is mistaken, even when the people using it are sincere.
We refuse the opposite error too. Genesis is not a made up story to be outgrown, and old rocks do not make God smaller. Nor are young earth believers foolish or less faithful. Many of them read the Bible more carefully than their critics do. On this one question we read it differently.
We are not settling here whether Adam was a single historical man. We left that open when we looked at where the Garden of Eden was, and it stays open.
Here is who pays when the date becomes a test of faith. Usually it is the young person who loves Jesus and also loves science, and gets told to pick one. Some pick science and walk away from a Jesus they were never asked to leave. That is a needless loss.
A test of whether you believe the Bible. A salvation issue. A reason to walk away from faith after a geology class.
One God made everything. Creation is good. People bear his image. God rests and reigns over what he made. None of it changes with the earth's age.
Your faith does not hang on a date. It hangs on a Person, and he was there at the beginning.
John opens his Gospel by echoing Genesis 1: “In the beginning was the Word.” He does not add a date. He adds a Person.
“All things were made by him; and without him was not any thing made that was made.”
John 1:3That is how we read the creation story, through Jesus. Colossians 1:16 says all things were created through him and for him. Genesis 1 is not a riddle about the calendar. It is the opening scene of a story that reaches its high point when the Creator steps into his creation, dies, rises and begins the new creation in everyone who belongs to him.
Six thousand years or four and a half billion, the question that matters stays the same: do you know the One who made it? His Kingdom is here now, and it has room for the geologist and the Sunday school teacher at the same table.
For related reading, see our overview of the book of Genesis, what God created on each day, whether the Bible says the earth is flat, what the Bible says about dinosaurs, how tall Adam was, whether the Bible is the Word of God, the new creation and what we believe.
The Bible never gives the earth's age, the 6,000 years comes from Ussher's math on genealogies that differ between manuscripts and skip generations, Christians read the days in several faithful ways, and Genesis points to the Creator whose name is Jesus.
If this question has shaken your faith or started an argument at home, send it our way. Someone at Sound of Heaven will pray with you and talk it through.
The Bible does not give an age for the earth. No verse states one. The popular figure of about 6,000 years comes from adding up the genealogies in Genesis 5 and 11 and the later history of Israel, most famously in James Ussher's 1650 chronology, which dated creation to 4004 BC. Those genealogies differ between the Hebrew and Greek texts, and they sometimes skip generations. Many faithful Christians accept the scientific age of about 4.54 billion years.
It comes from treating biblical genealogies as an unbroken timeline. Scholars added the ages of fathers at their sons' births from Adam to Abraham, then joined that to the later history of Israel. Archbishop James Ussher published the best known result in 1650, dating creation to the evening before October 23, 4004 BC. His dates were later printed in the margins of English Bibles, so many readers assumed the number came from Scripture itself.
Christians hold different views in good faith. Young earth believers read six ordinary days. Day-age readers see long periods. Framework readers see a literary structure where days one to three form spaces and days four to six fill them. John Walton reads the week as God inaugurating creation as his temple. At Sound of Heaven we read the days as a literary frame, true in what it teaches and never meant to measure time.
Yes. Nothing essential to the Christian faith depends on the earth's age. Origen and Augustine questioned an ordinary day reading of Genesis long before modern geology existed, and many believers today accept the U.S. Geological Survey figure of about 4.54 billion years. What Genesis teaches, that one God made everything, that creation is good and that people bear his image, stands whatever the date. Faith rests on Jesus, not on a number.
They may. Biblical genealogies sometimes skip generations. Matthew 1:8 names Joram as the father of Uzziah, while 1 Chronicles 3 shows three kings between them. Luke 3:36 includes a Cainan who appears in the Greek text of Genesis 11 but not in the Hebrew. The ages themselves also differ between the Hebrew, Greek and Samaritan texts. That makes the genealogies a shaky foundation for dating creation, however carefully the sums are done.
