I have been looking at the possiblity of there being a civilization that was wiped out approx 11000 years ago due to a massive sea level rise caused by a possible cosmic impact in North American.
The interesting thing is so many cultures have in their history a great flood. And although it is probable that any flood was not like the biblical flood it certainly seems from the ice cores a sea level rise of 30 feet within 24 hours did occur followed by a further rise of 400 feet over the following year or two...that could hide an earlier civilization ..if that happened to us it would mean places like New York and London would be 400 feet under water and covered by heaps of silt for folk looking 10,000 years from now.
So have you looked at this proposition at all...
The proposal is that a comet hit North America and that caused the sea to rise..there is a possible crator but as it is under a lot of ice they have not dated it as yet..but if that crator is dated at approx 12000 years ago it is clear that our history is different to that we have believed.
Have you looked at the possibility that a civilization existed and wiped out 12000 years ago.
It certainly seems most cultures talk of a flood which may suggest there is something to the findings of a dramatic sea level rise.
If the crator turns out to be 12000 years old will put history need to be rewritten?
