I agree, I would love to know how these ancient structures were built. And any theory makes more sense than aliens in UFOs.
i saw the bit on Discovery chanel. they erected obelisks using hemp rope and wooden truss's to support it as a kite pulled it into place.
they then move cut boulders the size of the ones in the Great Pyramids several yards in no time, and placed it neatly on top of and PRECISELY in place between the two. perfect stack, minmal time and man-power.
all you need is a few good engineers, sail-worth cloth, a few hundred yards of rope, some wood, and boulders. bingo, a pyramid in the time frames we see documented.
also, to back this up, they found that if you measure the winged hyroglyphics, the proportions are exactly what is needed for a level flight of a wing.....
this does come close to explaining Stonehenge... but damn.
I once saw a documentary about a guy that had moved to California about 75 years ago and proceeded to build a structure for the love of his life (she never showed.) He was using a configuration of magnets in the shape of a pyramid that was held up by a makeshift tripod. He used this to somehow move stones that weighed several tons by himself. He worked in secret and kept the details to himself. He claimed to have uncovered the secrets of the pyramid builders. I think that the structure still stands. Damn. I wish I could remember the details.
