I am an archaeologist (Ph.D.) and the vast majority of my colleagues and I say there was no global flood about 4350 years ago. (And, we have scientific evidence.)
(I am assuming your post was a jest on those who do cite a famous uncle as proof of some silly idea. Good one!)
Nope. He was an atheist until he started studying for his PhD and (gasp here) became a born again Christian.
Sorry he really does believe in creation and the flood. He uses geological research to preach.
