The Nazca Lines are these huge geoglyphs that the Nazca tribe made in Peru.

 The Nazca Lines are located in the Nazca Desert in southern Peru  This desert is an enigma just like the Nazca Lines itself

 Created between 200 BCE and 600 CE  Discovered in 1927

 First, the Nazca’s made a grid with the designs of the geoglyphs, and then enlarged it onto land.  Then, removed the dark red stone from the surface  Lastly, the Nazca’s ran along the paths where the geoglyphs would go to flatten the surface.

 I believe that the geoglyphs were used to show the symbols of different clans/groups.  I believe this because usually pictures or symbols show who you are or others around you symbolize.

I would test my theory by:  Researching the Nazca’s background  Then fitting all this information to figure out the puzzle why these geoglyphs were made.
