Stories about aliens have fed our fantasies for long and has found expression in popular art – from novels to movies. Among people who believe in the narrative are also those who also attribute the existence of strange places on Earth to extraterrestrial beings. To be sure, it’s fun to think about whether aliens have visited Earth. After all, humans are on the threshold of expanding our reach in space, and places like Mars are in our sight.
But the truth is, there’s no evidence suggesting that aliens have ever been here. And invoking a supernatural explanation for some of the most monumental of human achievements means skipping over the fascinating ways in which prehistoric civilizations managed to make some of the largest and most enigmatic constructions on Earth.
Teotihuacán, meaning the “City of the Gods,” is a sprawling, ancient city in Mexico that’s best known for its pyramidal temples and astronomical alignments. Built more than 2,000 years ago, Teotihuacán’s age, size, and complexity can make it seem otherworldly, but it’s very much the work of humans.
Scientists suspect that over centuries, a mix of cultures including Maya, Zapotec, and Mixtec built the city that could house more than 100,000 people. With its murals, tools, transportation system, and evidence of advanced agricultural practices, Teotihuacán is often considered much more technologically developed than should have been possible in pre-Aztec Mexico.
