(I'm sure it will shock none of you who aren't already familiar with him that he conned himself onto Rogan.)
Not to rain on Jimmy's parade, because I'm sure he's "done his research," but the Bible says that the Ark landed on the Mountains of Ararat, which is not the same thing as Mount Ararat. The connection with the mountain in Turkey didn't start until the middle ages.
Or, the end of the mini-ice-age resulted in flooding that equated to a rise of something like 20 stories (as in building levels) of water in lower regions including the Fertile Crescent. It would make sense that the first (known) civilizations would have great flood myths because their lands were wiped out during their lifetimes. Did the entire world flood? From their perspective yes. From that of geologists, no.
Edit: Oh, and I want to cancel all religions. Christianity isn’t special.
The sea level rise at the end of the Younger Dryas would have been virtually imperceptible to the people living through it.
Flood myths are because people generally settle near large bodies of water and large bodies of water can flood, sometimes catastrophically.
The Fall of Civilizations podcast indicated that there was a period of rapid rise in sea levels around Mesopotamia, but if you have reason to disagree with the host I’ll defer. I don’t know their background beyond being a good storyteller.
In geology, rapid is still a very long time, even up to a few million years.
