The conventional estimate for the number of stones in the Great Pyramid is over 2 million; in the 1990s there was a paper in KMT that made a more meticulous estimate and came up with something north of 5 million (there are many different sizes). A lot of work, regardless — even given that it’s likely that they weren’t quarried per se, but poured like cement.
Poured? First I’ve heard of that theory. Been watching Ancient Aliens, eh?
