Well hello there Mr. OP! I understand if you didn't see it at first, but I have a lovely proof against the flood over in
this post. Even framed as an experiment for your pleasure. The information regarding ancient cultures was gleaned through my minor in anthropology, a subject that has always fascinated me. If you want further explanation or support (as I'm sure you will, likely unable to accept the facts as presented) I will be happy to provide some books that you could check out. Unfortunately I won't be able to summarize three years of classes through forum posts, so unless you'd care to read up on the subject or take such classes yourself you'll have to take my word for it.
