As is any religious believer---but the point is that any form of creationism IS NOT SCIENCE, and cannot BE science. The question of creation is ultimately a metaphysical one.
"Within fifteen years, Darwinism was the accepted biological wisdom of German biology. Within a generation, most children in German secondary schools were being educated in its tenets."
So?? Actually it was the accepted biological wisdom of ALL BIOLOGY, not just German. I would HOPE that if a scientific discovery of that magnitude were to be made today that "most children in ......secondary schools" would become educated in its tenets "within a generation".
If one takes it that the Resurrection actually took place, then it is as much a fact as that a peach tree bears fruit.
Darwin discovered nothing. He was not the first person to posit evolution. What he did propose was a mechanism by which the descendents of certain animals became a different sort of animal. He was not even unique in discerning this and his theory was by no means universally accepted by geologists, who did not see and do not see the fossil record that Darwin predicted. This does not disprove his theory, but only goes to show that
many people lept to a conclusion they found attractive, just as many others dismissed it out of hand.
