There are a bunch of weird/stupid theories, but the fact that they moved stones that weighed up to 80 tons, 800 kilometers from the quarries and then hoisted them 450' high is mind boggling. Not possible it was done with barges because the barge would be bigger than the damn canal - simple math proves that wrong. The precise cuts on these stones, the precision of the joints, the precision of the layout (the whole thing is only a half inch off from square) and the holes that are drilled defy explanation. There's no way they were drilled and cut with copper chisels and sand.
The claimed age of the sphinx in in question as the amount of erosion points to it being possibly 13,000+ years old. And the pyramids could be the same age. Since you can't carbon date stones we can't really tell how old they really are. They could have been built by an older civilization & inherited by the Egyptians. Usually build quality gets better over time as techniques improve, but the pyramids are the opposite - the newest ones are not even close to quality of the oldest ones.
Then there are the vases and boxes in the pyramid that are unbelievably precise - too precise for them to be hand cut.
This is a cool clip. This Ben Van Kerkwyk is a fun listen on this subject. So is Graham Hancock.
