The Graham Hancock shit never ceases to amaze me. Supposedly there was a super intelligent civilization living on Antarctic continent when Earth was in a different position, Antarctica was a lush paradise while North America was on the South Pole and a frozen wasteland. I think maybe these people had some Nichola Tesla shit going on with all these structures, wireless power grid and some technology that was completely lost when the poles shifted and their home continent became frozen under hundreds of miles of ice.
I read that there was once a super Earthquake at Yellowstone, it was so bad that entire mountain ranges disappeared into lakes of volcanic lava, just gone forever, entire fucking mountain ranges vanished without a trace. So just think about what all would be lost without a trace if there was some super global catastrophe like a pole shift. I think it's possible that people were once smarter than what we are today, maybe they had electricity, internet(or something like it), other technologies that would go beyond our comprehension, the whole works, then it all came tumbling down and the whole species had to start over from scratch and we have amnesia.
