Atlantis and the Garden of Eden

If you read the Bible literally in Genesis on Eden, it states that there were giants in those days, if the giants were people then it would have most likely have been during the time of the Cro-Magnon man. If you take it as dinosaurs then it may have been during the time of the dinosaurs, and possibly on Pangea the single conglomeration of all the continents! Also it mentions of the area to the east of Ethiopia in the Bible, which would either be still in Africa depending how far away, or in Saudi Arabia, or India, (which is the more likely scenario, since more and more findings from India to the Indonesian Islands are coming up with more and more earlier periods of civilization, let alone the Hindu Mahabarata descriptions of their early civilization.
