Here is an area of South America, in Peru. The section that we need to examine is about 70 miles long by about 25 miles wide. It's very dry and stony so that it has remained the same for hundreds, perhaps thousands, of years. It's the plain of Nazca. The location :

To give you some idea of the scale, from the capital of Peru, Lima, to Arequipa in the south by a straight line is about 460 miles. The Nazca we are interested in is the one next to the "E" of the Andes mountains, not the Nazca on the coast next to the Pacific ocean.

The site was first discovered in the 1920s AD as a result of air travel in the area. On that plain there are markings created by displacing the stones or small rocks to show the lighter coloured underburden. There are huge trapezoidal areas:

There are clear representations of animals, and birds:

and there are geometric designs:

All these designs are hundreds of feet long. There are lines that run perfectly straight for miles:

In the foreground modern vehicle tracks cross the Nazca line. We can see that these original Nazca shapes, designs and lines are not natural markings. Some intelligent agency must have created them. The problem is: who created them, when, why, and how.
