The Maya prophecy did not predict the end of the world on December 21st, 2012, but a change of cycle in the Mayan calendar.
The end of the world is described in two stones engraved over 1300 years ago, in the 7th century AC. Both were found within a short distance of each other in the state of Tabasco. A small brick located in Comalcalco and Monument 6 of Tortuguero. The message is brief. Once the 13th B'ak'tun is over, on December 21st, 2012, a God known as Bolon Yokte'K'u - the Lord of the Light - will descend from the heavens and a new 5,125 year cycle will be completed.
It can be argued that the Maya never mentioned the end of the world nor time, as their writings on dates beyond 2012 prove. Epigraphists note there are references to dates as far as 2,000 years ahead, in 4772, at the Temple of Inscriptions in Palenque.
