Some suggest it does not. Others allege that the Bible simply does not speak to this matter. If it is true that the Bible is completely silent on this topic, then certainly we ought not to make an issue of it. The average layman thinks there is, but he is mistaken. Radiometric methods for dating the earth's rocks are based upon the decay sequences of certain elements.
Scientists believe they know the present decay rate.
It is conceded, however, that in order for this method to be valid, certain assumptions must be granted. It must be assumed that no lead-206 was in the rock at the time of its formation. That would invalidate the accuracy of the age-estimate. It must be assumed that neither the parent nor the daughter element has been altered in mass since the beginning. However, there is an increasing body of evidence which indicates that both parent and daughter elements, under the proper conditions, can migrate in the rocks, thus radically affecting any result that might be obtained.
