Huh, my uncle who is a geologist (PhD) says there WAS a global flood.
If there was a global flood, can you tell me where all the water went?
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!)
I don’t think there’s enough water on the planet to produce a global flood, but since your uncle is a geology PhD, surely you can find a cite from a geological source that there was a global flood four thousand years ago. Otherwise, I say... phooey.
