OK, I read it. Until now, I thought I had seen everything.
Turns out..perhaps everything we know is wrong.
It kind of "unbundled" at roughly the time the Sumerians were learning to count and write ~ and probably passed quite close to Earth as it was slowed into an orbit a bit closer to the Sun.
Venus, BTW, is Ishtar, the Sumerian chief goddess. There's a story about Inkydoo you need to look at since Inkydoo was created After Gilgamesh (who may be the Moon), and he had lots of hair (like a cometary body).
Depending on how close this now Venerian moon got to the Earth, if it came across the Mediterranean basin close enough it would have pulled up plenty of water to both cut a channel to the Black Lake so it could become the Black Sea, and create locally disastrous floods for everybody between Spain and New Guinea ~ water rising as high as the mountains in a gravitational battle between this little moon and the Earth.
With the Sumerians the ONLY people on the planet with writing at the time their story would become the basis of the whole flood mythos. As writing spread, the flood story spread.
