Serious question - if that is the case, how do we explain the astronomical alignments of ancient megaliths? I'm not sure what believed date is for the Piri Reis map, but if memory serves it might be a couple thousand years?

That's a far cry from 12,000 years back when many of the megaliths were lining up. So presumably, if they're still lined up (within the expected wobble) then there has been no pole shift or related thing since they were built....?

I'm askin' here, not tellin'... sincerely curious.
