The Nasca Lines of Peru: ancient images of animals and vast geometric designs etched in the desert ground â have mystified the world for nearly a century. Some have speculated that aliens built them. Employing drone camera technology, Peruvian archaeologists Luis Jaime Castillo and Johny Isla have discovered even older lines in the Atacama Desert, some more than 2000 years old. Unlike the known Nasca Lines, these older lines depict humans, such as dancers and warriors. This image is from Nasca Lines: Unlocking The Secrets.
