I don't know how long the flooding would have taken. Do you? It might well have been prudent to build a boat to travel the area and find out whether the water withdraws or not.
doesn't matter the water only went up 100 feet. the level it is at now.
Either way, most cultures assumed that the world they knew was the entire world. So any flood destroying their world was, obviously, a flood destroying the entire world. That doesn't mean that they knew anything about the flood's impact (or non-impact) on other regions.
but that doesn't explain the similarities in the story.
only a small group of people survived the flood.
again Gilgamesh about a flood that washed a merchant out to sea. that would be a local flood.
the black sea would have destroyed the world around the black sea. but since it didn't cover any mountains. that doesn't correspond with the Noah story.
nor does it explain why there are only a small group of animals on the planet. there are only about 200 types of animals on the planet. yes there are thousands of species but their all related to each other.
