I doubt it. As I understand it, Gilgamesh is the same individual as Noah. I think the great flood was an earlier event (consider the Black Sea flooding nearer to Ararat), but I would give a Lot more credence on this one explaining Sodom and Gamorrah.
Atlantis is under the ice-cap in Antarctica... it was habitable before the pole change. That's why it has never been found.
The flood parable is consistent in all ancient cultures... it was no local thing.
I've never heard this before. I'll see (later) if I can get some dates to connect on this Gilgamesh/Noah thing.
I've been trying to connect the refugees from the Black Sea flood to the caucasian mummies found in eastern China, The Mummies Of Urumchi, Elizabeth Barber and The Tarim Mummies, Victor Mair. (both excellent books)
The Black Sea Flood (Noah's Flood?) occurred 7,600 years ago. (Ryan & Pittman, Noah's Flood) Gilgamesh ruled Babylonia about 2,700BC (4,700 years ago). I believe the Gilgamesh/Noah story are taken from the same event. Whether they were the same person, don't know. There's a 2,900 year gap between the flood (Black Sea) and when Gilgamesh ruled Babylonia. That's a reeeaaal long time interval. (Are we back to the possibility of two floods?) I expect so.
