Maya people were masters of mathematics and calendars and they were keeping track of time using three separate calendars. For predictions about the beginning and end of the “world” they used “Long Count” calendar. And on December 21st 2012, the Long Count will be at the point zero which Maya predicts as the end of time and beginning of the new world.
The Mayas were very accurate in their predictions and they predicted invasions on their soil and the World Wars. Most interesting fact about Mayans was their artificial cranial deformation practice. They believed that flat heads represent nobility so they flattened babies heads with two large sticks and newborns were left for days to endure pain.
When Spanish missionaries arrived, for them, one of the most surprising things was the deformity of the Mayans heads. Some wrote that in certain cases you could openings behind the Mayans ears. Some believe that Mayans tried to look like someone. Maybe early alien visitors?
