There is a branch of archalology where they do replicate ancient techniques by trying them, including stone fitting, moving large stones, and carving without machines. The techniques do work with a little practice.
The cutting rocks one is actually a lot more simple than it looks, you cut a stone till it looks like it will fit, then put sand on the stone you are matching it too. Find the uneven indentation marks in the sand and then work on those areas some more. I have seen this demonstrated.
A stone the size of the ones at stonehenge was moved by experimental archeologists with tools available at the time.

Some trial and error and 130 people got the job done.
As for the human hair claim... do you have a verifiable source? A line in tension as a guide, like a chalk line, might be a place to start on that one.
"If its so easy to do, why don't you guys that are making that claim just go do it?"
Archeologists do go out and do that, so do scientists. Thier work is reviewed critically by experts. The show Ancient aliens makes fantastic claims and offers no real evidence. It Ignores or contradicts things which people have already "gone out and done" and had peer veviewed.
Frankly I don't care if you think I am "the type of person [you] really dislike the most."
The show bugs me because it tosses out wild unsubstantiated claims that sucks a lot of people in. Shows like that on a channel that at one time had actual educational value (it was not proffitable so they got rid of it) just make the general populace dumber.
