Throughout time, people have claimed to know exactly where Atlantis was located. Unfortunately for them, it was virtually impossible for them to prove it. Until recently, the ocean floor was a vast mystery. Now that we have some accurate measurements, depths, maps and pictures of the ocean floors, the door is wide open for conjecture about where Atlantis now lies. Everybody seems to have their own ideas about where the legendary lost continent of Atlantis is located.
Theories range from Antarctica to Indonesia, from the Americas to Australia.
Since there are so many theories and one block is such a short time, we're only looking at the Atlantic ocean here. I'm not saying that there isn't evidence that Atlantis existed elsewhere in the world. Here, if you're interested, I'll throw in a little page about Thera in the Mediterranean.
