311 - The Nazca Lines

The Nazca lines have become famous over the years for their mysterious origins and purpose.  Residing in the high desert in Southern Peru, the lines were created by removing the top layer of desert rocks, exposing the different colored clay beneath.  Some of the lines appear to be an astronomical calendar, some are drawings of birds and beasts, and some seem to have no known purpose. The mystery of their purpose has led to them becoming a favorite topic of the pseudoscience community in recent decades as evidence of ancient aliens.  Take a listen and see what we do know about them, when they were made, and what their purpose might be.
