As our Cessna plane lifts off the Nazca airport runway and banks hard to the right my thoughts are about the geoglyphs I’ll see. I’ve seen these in pictures and documentaries but now I get to see them personally. What are the Nazca lines? Why and how were they made? By or for aliens, for the Gods, for some reason yet to be discovered? Looking down at the ground I realize the actual complexity of these criss-crossing lines and the vastness of the area they cover.
