The Aztecs believed that our world was created 5 times, and 4 times destroyed before; these are the so-called "Five Suns". I know that the present epoch by the Aztec calendar, i.e. the "Fifth Sun", began on 3113 BCE. What are the dates of the previous 4 "Suns"?
The 3113 BCE date comes from the Classic Maya calendar. According to the ancient Maya, the current baktun, or creation period, started on August 11, 3113 BC, written in the Maya calendar system as 0.0.0.0.0 4 Ajaw 8 Kumku. The date and its significance are explained in the inscriptions of Palenque, Mexico, and Quirigua, Guatemala. It looks like someone is borrowing from the Maya to date the start of the Aztec First Sun. In fact, the Aztecs did not date the start of the First Sun in any form that modern scholars can recognize.
