Worm Holes ain't like computers, they wont take you to an exact time period.

The rise of the Maya refers to the period in Mesoamerican history when the Maya civilization began to develop and flourish, around 2000 BCE. During this time, the Maya built sophisticated cities, developed a complex writing system, made advances in mathematics and astronomy, and created impressive artwork. This period of growth lasted until around 900 CE when many Maya cities were abandoned for reasons that are still not fully understood.
