If you are thinking of purchasing this dvd do so with an understanding that its highly entertaining, nicely done but utter nonsense. No archaeologists or credible scientists are properly interviewed and its full of converts - people with a vested interest in selling their books or magazines. For each issue there are more plausible alternative explanations. Look at the notion that its too much work to carve rock so ancient Egyptians had magical alien technology. Its obvious Egyptian stone masons had plenty of time and got the job done by hard work. But only the one view is puched and pushed. Its fun, but its fun of loonies.
