That is incorrect. Provide any reference if you feel otherwise. The Aztec were in the area of we now refer to as Central Mexico.

There have been no Aztec ruins ever discovered in what is now known as the United States.
According to Aztec legend, they came from far to the north, which Mexican racists take to mean the SW USA and draw the conclusions I mentioned from this "fact."
The Aztecs are fairly closely related linguistically to the Utes and other SW American tribes, FWIW.
There is, BTW, some evidence that the move of the "Anasazi" into their cliff dwellings was related to an increase in Meso-American influence, perhaps even "missionaries" from what is now Mexico.
If the neighbors got into human sacrifice and cannibalism, I'd move into a cliff dwelling, too.

Actually not true. Just outside the town of Aztec, NM there is a large ruin that is called "Aztec Ruin." Nothing to do with the actual Aztecs, of course, but still an Aztec ruin.
Obama hates this country and wants to destroy it. It is a long tradition for Africans to poop in their own nests.
