Jason Colavito recently posted a picture worth a thousand of von Daniken’s words over at his blog. A good illustration of some photographic sleight of hand that draws in the gullible when it comes to ancient astronauts. Check it out at “Are Inca Walls Too Big for Humans to Build?“
I don’t believe in ancient astronaut nonsense, but I don’t think Colavito’s argument is entirely fair. He gives the impression that none of the walls are really big which is proven when they are photographed together with humans. The wall on the picture is located in Cuzco downtown where you won’t find any really impressive walls (that said, the guy in the front is standing by “the 12-sided stone”, probably the most photographed stone in Peru). Now, if you walk just outside Cuzco, to the fortress Sacsaywaman, you’ll find walls made of really huge rocks (try Google).
Okay, I read too fast; he mentions Sacsaywaman.
