Radiometrically dating adjacent rocks

However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over 500 million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.If these dates are correct, this calls the Biblical account of a recent creation of life into question.

Since no part of the lithification process would reset the 'atomic clock' within individual minerals any date measured would represent the time the individual mineral grain crystallized not the time the sedimentary rock was lithified.We are told that these methods are accurate to a few percent, and that there are many different methods.We are told that of all the radiometric dates that are measured, only a few percent are anomalous.In this processes scientist compare the ratio of Carbon 12, a stable isotope of carbon, to that of Carbon 14, the radioactive isotope.Both Carbon 12 and Carbon 14 occur naturally within our environment at a constant ratio (although carbon 14 is constantly decaying new carbon 14 is produced in the upper atmosphere as Nitrogen 14 is bombarded by cosmic radiation).
