The Mystery of Aztec Artifacts

The Aztec artifacts are examples of a really nice place for me where mystery kind of comes into reality. Just imagining someone that far back in time constructing this thing with tools available to them would be pretty awesome. I heard back when I was a we type that no Mesoamerican culture had invented the wheel when they were encountering other cultures. Did you guys ever hear that? No, no, I'd have to get into that.
