How did the Egyptians move 5000 lbs. blocks hundreds of miles to build the pyramids.?
They didn’t move them hundreds of miles, they were quarried near where the pyramids were built. This wasn’t known until recently because the quarries were filled in with rubble. They knew about levers, pulleys, etc., so they had little difficulty moving the blocks, with the amount of labor they had available. It is a mistake to think that people long ago knew almost nothing. Many modern people have much less knowledge about certain kinds of things than people thousands of years ago.
