 It might take the reason I wrote before Atlantis was to think of Atlantis not so much as a place but more as a time, which was an ice age or a civilization that existed during the last ice age. The ice age was in North America, but the rest of the world did not have an ice age. When we had an ice age, Central America had a very temperate climate, and I think this was a big part of where Atlantis was.
