I've been to Peru twice and wife wants to go again. I don't but anyway, I didn't see the nazca line though they always interested me. I think it's a tribute to the math of the ancients more than UFO's or anything too mysterios. Perhaps they had methods of seeing their completed work?

The strains are a sort of geometrical figures, trapezoids, triangles and strains, plus marine, animal and chook figures of hummingbirds, a whale, a monkey, a spider, a chook likened to a pelican, yet another like a condor, and one referred to as the astronaut. they vary in length as much as one thousand feet (300m) throughout the time of and are approximately 2000 years previous.
