"I think that's naive."
Who cares what you think?
"How long have we all been led to believe the pyramids were designed to be tombs for the pharaohs, or that the "Stone of the Pregnant Woman" is an unfinished megalith still partialily attached to bedrock in the so-called "Roman quarry" in Baalbek?"
As for myself, never, as my posts consistently validate since Day 1 on this forum. But what you "have been led to believe" is entirely a matter for you.
"Would you mind sharing your specific source for that information?"
