No. There are a number of interesting theories as to how the Egyptians could move the stones of the pyramids vertically and from the place they were quarried. The coolest involves simple physics. Check out the website (with video) of this retired construction worker from Michigan. It’s amazing how this guy moves multi-ton stones by himself. Yeah, I bought his CD, too, so I could watch the full videos. You should, too, if you want to ward off the alien astronaut crowd (“Nobody I know could have thought of this technology, so it must be aliens”). Yeah.
