How does the evidence of life on earth millions of years ago equate with the Bible claim that God created life on earth recently by comparison? Starting with a deep commitment to the inerrancy of God s Word, has calculated a span of just a few thousand years, most likely close to 6000 years, since creation. The age of the earth can be estimated by taking the first five days of creation (from earth’s creation to Adam), then following the genealogies from Adam to Abraham in Genesis 5 and 11, then adding in the time from Abraham to today. Adam was created on day 6, so there were five days before him. If we add up the dates from Adam to Abraham, we get about 2,000 years, using the Masoretic Hebrew text of Genesis 5 and 11.3 Whether Christian or secular, most scholars would agree that Abraham lived about 2,000 B.C. (4,000 years ago). Historians date Abraham s biblical story around 2000 B.C., based on clues in Genesis Chapters 11 through 25. So a simple calculation is: 5 days + 2000 years + 4000 years = 6000 years.
