A lot of cultures arose around rivers, so it’s not surprising that there are a lot of flood myths.
And the creation of the Black Sea probably played a part.
But proponents of the Biblical flood seem to be talking about a flood that covered the entire world as we know it today.
Oh, I know.
I offer another literal reading of Genesis, unadulterated by Western thought.
I mean “World War I” didn’t have the whole world in it, did it? Heck, it barely had all of Europe. But it is still “world war.”
