A few possible scenarios have been suggested in respect to dating these sites. One possibility is
that they may have been submerged when sea levels rose as the continental ice sheets melted at
the end of the last Ice Age. Another one is that because Japan sits on the edge of the Pacific ‘Ring
of Fire’, tectonic activity might have caused some type of massive land subsidence and this is not
at all unlikely. Teruaki Ishii, who is a professor of geology at Tokyo University, suggests a date
contemporaneous with the ancient civilizations of Mesopotamia and the Indus Valley for the
ruins, putting them at about 8,000 B.C. while others have suggested an age of around 12,000 BP.
Fig.101There is every indication that more than one ancient civilization may well have existed on the
earth and indeed, every possibility that a civilization preceding even the one which we know as
Atlantis may well have even existed.
As you read further you will see why this is not a wholly unlikely or impossible scenario.
