Peru's famous Nazca Lines are a mystery. They are huge geolyphs that can only be viewed properly from high above, yet they are ancient designs from before any aircraft was known to exist.
Pre-Columbian native societies in Central America were known for building pyramids, much like the ancient Egyptians were known for building pyramids on the other side of the world. The design and purported use may not be exactly the same, but the resemblance is still there.
But one South American native culture may have something in common with ancient Middle Easterners too. Satellite and aerial photography have now revealed mysterious stone structures in the Middle East that are more numerous and older than the Nazca Lines.
