Atlantis myth

My theory is that the disappearance of Atlantis is equivalent to the "Great Flood" and the story of Baucis and Philemon.

ABC had a special on about a week ago promoting their new movie Atlantis and they said that some oceanographers think they have found Atlantis. They say that Cuba once was a much larger island that was home to an advanced civilization. Some native American cultures have stories of a great snake in the sky that caused massive flooding. They say this was a comet's tail that looked like a snake and the flooding wiped out the southern 3/4 of Cuba. They had a quote from Plato making it sound like trips were regularly made from Greece to Atlantis.
