Perhaps if the question is who created the entire universe who who invented the levitation
guns that lifted the stones to build the great pyramids it becomes pretty tough to answer without
invoking gods or aliens. I know some pretty sharp people but not one of them has ever flown to
another planet and built large piles of stone.
Most people I encounter would starve to death or die of exposure first if they had to live by their
wits alone. If someone hadn't first invented language and the computer it would be pretty difficult
for you to even express you skepticism.
Maybe the pyramid was just a bet between a couple aliens that humans would in no time come to
believe we had built the pyramids despite the near total lack of evidence for how stones were lifted.
