I've always found this attitude to be essentially a prejudicial opinion against people in the past that says they weren't clever enough to move giant blocks of stone. Therefore it must have been aliens/chariots of the gods/crystal power.
I've always found this attitude to be essentially a prejudicial opinion against people in the past that says they weren't clever enough to move giant blocks of stone. In the Third Temple in Jerusalem there was a stone block that is still there. The block is (IIRC) twice as big as the biggest stones at Giza.
And there is no way it was built by little gray men.
It can be done, it has been done, the only question is exactly how it was done and when.
