I know I'm joining this conversation a bit late.......apologies.
But I am a very big Atlantis enthusiast/scholar.
To paraphrase one of the earlier posts: "I believe that a place that we today call Atlantis existed".
Surely it did!! There is too much overwhelming evidence of it to deny it. WHERE? Well, that is the big problem. I think that it is apparent that Atlantis did not exist in the middle of the Atlantic Ocean. But there are many, and varied theories on where it existed. I personally favor a few: I believe in the possibility that "Atlantis" was a seagoing empire that existed along the coasts of several continents, including both North and South America. Or perhaps it was a meditteranean based nation/state. Another theory I favor is that it was a North African locale.........and that the descendants were the Phonecians.... and of course.......the Egyptians.
I have read Plato..........I have studied the evidence.......I have studied the Piri Reis maps. The Bible, among numerous other historical and mythical records describes in detail the Earth catastrophes that are mirrored in the Atlantean record.
I am a strong believer and supporter (which puts me in the company of a certain,........um......famous..... scientist whose initials are A.E.) of Charles Hapgood's theory of Earth crustal displacement.
I could go on all night, but ....................
