The Mayan and Hindu calendars both divide history into eras, and the epochs (start date) of their current eras lie extremely closely together: August 11, 3114 BCE (Mayan) vs. 18 February, 3102 BCE (Hindu), a difference of only 12 years.
Are there any scientific theories that attempt to explain this as anything other than a coincidence? In particular, are either of the following thought possible:
- Both epochs represent the date of a global event (natural disaster) witnessed by ancestors to both civilizations
- The civilizations were in direct contact with each other (seems unlikely)
- The founders of the Mayan civilization migrated to the Americas from Asia at a time when the Hindu calendar was already in use (seems extremely unlikely)
I want to emphasize that I am not asking about random speculations here, which are of course easy to find on the Internet, especially in connection with the Mayan calendar. But surely, the close correlation must have been noticed before and I am interested in what others have made of it.
