NASA and Ancient Space Sites: The Story of a Plan to Leave Earth

In 2003, heavy rain opened a sinkhole beneath the Temple of the Feathered Serpent at Teotihuacan in Mexico. Archaeologists found the entrance to a tunnel about 103 metres long and 18 metres below ground. It led to three chambers sealed for centuries. In 2015, Sergio Gómez’s team found a small amount of liquid mercury at the deepest point, along with pyrite that could reflect light and thousands of offerings.

The official explanation is a ritual space built to represent the underworld. Look at the physical details first: a deliberately cut underground structure, a floor shaped with ridges and channels, liquid metal placed inside a closed chamber, and an entrance blocked after the objects were deposited. If it was only a shrine, why did its builders create a complex underground system and hide it for almost two thousand years?
