Deep in the Amazon forest lie secrets that contradict the very foundations of mainstream history. These jungle secrets are so different from what we thought we knew about the previous history of the Amazon and human civilization in South America. Researchers have made an ancient discovery that shows that long before the Incas, Maya or Aztecs, other peoples lived on the continent and shaped Mesoamerican culture. Some of these mysterious peoples are believed to be living deep in the jungle to this day.
