Where are Aztec Indians from?

Answer 1

The term "Aztec" refers to certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to 16th centuries. The Nahua peoples began to migrate into Mesoamerica from northern Mexico in the 6th century. They populated central Mexico dislocating speakers of Oto-Manguean languages as they spread their political influence south.

Anthropologists are not in universal agreement on the ultimate origins of these people (prior to their migration from northern Mexico). The dominant theory is that they were migrants from even earlier indigenous cultures residing in what is now the American Southwest, which in turn were descended from the Clovis culture. Some interesting competing and/or augmenting theories include those of Thor Heyerdal who demonstrated the feasibility of people crossing the Atlantic Ocean on papyrus rafts (which might explain the Mesoamerican stepped pyramids) or even the Book of Mormon explanation that some of their ancestors might have come from people fleeing the Near East just prior to the Babylonian conquest of the area.
