Wherever it was is probably now underwater, and it will probably remain forever prehistoric, even if it is someday found. But Crete wasn’t Atlantis. It was, however, Tarshish.

I have never studied Atlantis in depth but a few things are obvious. First, Plato’s account cannot be accurate. Second, no one really knows where or even if it existed.
I do think Plato was referring to a specific place. I always thought Crete fit the description better than any other place.
I also always thought Tarshish was ancient Tyre or at least Phoenicia.
