When I was young, one of my aunts who was really into bizarre stuff showed me this article in one of her tabloids about some Aztec art that supposedly depicted a US astronaught-like image. They showed this photograph of the mural being sculpted supposedly right in the side of one of the pyramids. It really looked amazing, and got me interested in Aztec art and the culture very much.

Although thinking back on it the image was probably a fake, the idea still stands that Aztec art (and the culture) demonstrate signs of advanced technology. Much like the Egyptians, this culture was very dominant, very fast. Their quick rise to power and large civilizations had to have some technology that was vastly superior to those around them and, knowing that the Egyptians had drawings of lightbulbs, surgery and even helicopters in their pyramids - it is a very likely possibility that something like what I had seen in that photograph many years ago is probably true.

In the end, that was such a long time ago that it really is a matter of how open your mind is to something like that. We will never really know for sure...
