I agree with Dean, the problem as to how they did it was resolved ages ago. They know the quarry the rocks came from, how they were transported, and then erected.
Clever video though. Clearly got time on his hands.
BTW, I passed through Glastonbury and Stonehenge at the weekend. Very mystical I must say.

("If I had to select one quality, one personal characteristic that I regard as being most highly correlated with success, whatever the field, I would pick the trait of persistence. Determination. The will to endure to the end, to get knocked down seventy times and get up off the floor saying "Here goes number seventy-one" - Richard M. DeVos)
