If you found Atlantis, how would you know?

In reviewing my notes for my talk next Saturday in Portland, Oregon, on Atlantis and its Colony in Egypt, I wonder again, how would you prove some ancient civilization actually was Atlantis?

It isn’t as if there would be a sign that said, “Atlantis.” Who knows what Atlanteans had called themselves or what, if any, language they used? Maybe they had no written language at all or anyway, no language like any on earth at this time. How would you know it was Atlantis and not some other ancient civilization?
