"If, during early creation week, say before the creation of man, such variations were to occur, they could lead to accelerated nuclear decay, thus adjusting isotopic abundances, without giving humans an unacceptable dose of radiation."
And we always hear that evolutionists engage in wil speculation. ; )
First of all, creationists believe that the geologic column, since it contains fossils (of course), came after the fall of man (when death supposedly entered the world). So why would radiometric dates of millions of years appear long after the alleged creation, after these alleged variances occured? Secondly, geologists use something known as the principle of superposition. It states that all layers of the geologic column were originally layed down horizontally, with the older on the bottom and the younger at the top. Why would radiometric dating agee with this if it was wrong?
