If the reporter had done even a little bit of research he'd have learned that pre-Columbian cultures in Mexico and southwards believed caves were sacred. Their creation myths said humans came from the Underworld, so pyramids were often built above sacred caves.

This was definitely a belief of the Maya and contact between the Maya and the unknown builders of Teotihuacan has been proven. Mayan artifacts have been found in Teotihuacan.

I'm personally of the opinion that that the Olmec, the Maya and the builders of Teotihuacan shared common cultural roots.

The Toltecs as well as the Mayans are largely considered to be the leading candidates for Teotihuacan. The Aztecs just found it and considered it a sacred place.
