by Lita Cosner Many people write in and ask, “How do we know that the earth is 6,000 years old from the Bible?” Given that the chronogenealogies—genealogies where the age of the father at the time of the son’s birth is given in an unbroken chain—end shortly after Noah, how do we get from ~1600 The precision by which we can know the timing of historical events or ages of things is constrained by the precision of the data we’re given.
When nature disagrees with scripture, scripture must necessarily be wrong.
Nature tells us Ussher was off by six orders of magnitude. Buy a magnifying class and a box of Twinkies and visit a dendro lab.
There is no independent natural clock against which those assumptions can be tested.
For example, the amount of cratering on the moon, based on currently observed cratering rates, would suggest that the moon is quite old.
True, scientific progress repeatedly found our home to be much older than previously suspected, but the widespread view that the planet is only a few thousand years old is relatively new, and has no basis in either fact or scripture.
The 6,000 year age was arrived at by James Ussher, a 17th century Irish Archbishop who counted up estimates of the ages of Abraham's family listed in the Old Testament and calculated that the creation began (on the Julian calendar) on Saturday, October 22, 4004 BC, at 6 pm. Usher made a lot of assumptions, chose to ignore inconsistencies within even those scriptural sources known at that time, and was unaware of certain, now obvious translation issues, importantly including the way the Babylonians counted, but that's beside the point.
As indicated earlier, the Bible does not fix the age of the earth, contrary to the claims of Answers in Genesis.
Historically, their claim comes from the work of James Ussher, Bishop in the Church of Ireland, from 1625 to 1656.
the age of the earth and the universe, and that includes the ones we have listed here.
