Mayan Calendar Stone

What the Show Claims

• ›Ancient Aliens suggests the Mayan calendar's precise astronomical calculations and end-date prophecies indicate contact with alien intelligences who provided advanced mathematical and astronomical knowledge to the Maya.

Mayan calendrical systems are well-understood by scholars as sophisticated independently-developed mathematical and astronomical achievements. The calendar's long count cycle ending in 2012 was interpreted by some as apocalyptic, but archaeologists note the Maya themselves did not view this as a true 'end date.'
