My point wasn't that each flood has always been detrimental, but that there has never been a collection of people living in a place where there aren't also dangerous floods that kill people, so wild stories of floods destroying the world aren't really far out for the lived experience (perhaps across a few generations) of any human ever.

Got it. Yes indeed. That makes total sense and I agree.

Also at some point in prehistory the rock formation that is now the strait of Gibraltar fractured and the Atlantic ocean rushed in and drowned the entire basin of the Mediterranean,[1] so that type of cataclysm has actually occurred, although before human experience
