Well played. Now let's have the fundy tell us how water covered the earth and drowned everybody but then the world was repopulated. Wait… is there some incest required for that to be true? OH NO!
Noah is a Babylonian "deluge myth". Judaism didn't even exist until 1,000 years later:
It tells of how Enki, speaking through a reed wall,[v] warns the hero Atra-Hasis ('extremely wise') of Enlil's plan to destroy mankind by flood, telling the hero to dismantle his house (perhaps to provide a construction site) and build a boat to escape
This means that originally the flood was caused by one god and mankind was saved by another. That's a better explanation than "God was angry but bipolar, so he saved one family and killed everyone else."
