Carbon dating seal
New-earth creationists obviously cannot accept the accuracy of the C-14 dating method.For example: Scientists have dated a female figurine commonly called the Venus of Willendorf or the Woman of Willendorf to 24,000 to 22,000 BCE.Take the extinction of Neanderthals, which occurred in western Europe less than 30,000 years ago.Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals' demise.Carbon dating is used to work out the age of organic material — in effect, any living thing.The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.They were unable to date the object directly since it is made from oolitic limestone.
Marine records, such as corals, have been used to push farther back in time, but these are less robust because levels of carbon-14 in the atmosphere and the ocean are not identical and tend shift with changes in ocean circulation.
Since the 1960s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings.
As a rule, carbon dates are younger than calendar dates: a bone carbon-dated to 10,000 years is around 11,000 years old, and 20,000 carbon years roughly equates to 24,000 calendar years.
Creation scientists cannot accept these dates as accurate since they believe that the world was created sometime between 40 BCE.
Since the accuracy of the Bible cannot be questioned, C-14 dating must contain massive errors -- by as much as a factor of five.
The recalibrated clock won’t force archaeologists to abandon old measurements wholesale, says Bronk Ramsey, but it could help to narrow the window of key events in human history.
