Carbon dating the history of life on earth
Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).Most carbon-14 quickly combines with oxygen to form radioactive carbon dioxide, which then spreads throughout the atmosphere.
They concluded that their findings are consistent with an Earth that is about 6,000 years old.As our knowledge continues to grow, what we know continues to be in agreement with Scripture.Radiocarbon ages less than 3,500 years old are probably accurate.Plants take in carbon dioxide, incorporating in their tissues both carbon-14 (unstable) and normal carbon-12 (stable) in the same proportion as they occur in the atmosphere .
Carbon-14 then moves up the various food chains to enter animal tissueagain, in about the same ratio carbon-14 has with carbon-12 in the atmosphere.
Therefore, a radiocarbon year would not correspond to an actual year.
