I would still like to direct our collective intellectual power to why we assume that Atlantis is to be found in the Atlantic. Is it a psychological trap we fall into because of the similarity in names? Or is it because we want it to be close to home? Will we feel we were a bigger part of it if were next door, instead of far away?
Are our emotions ruling our logic? We all empathise with the legend strongly. Something in our subconscious wants it to be true.
Why do most of us assume it to be in the Atlantic, instead of the Pacific, or Indian Oceans (as we call them today)? "Beyond the pillars of Heracles" means outside the straits of Gibralter, ruling out Thera in the Mediterranean.
So where are continent-sized (the size of Libya [Africa] and Asia-Minor combined) that would have disappeared quickly around 9000 BCE?
