At the risk of disillusioning all those who believe that many of the works found throughout the world have been made by or for extraterrestrial beings, I will tell you that I think the Nazca lines have been made by men.

For this to have been possible, the following conditions must have been met:

These lines were made in peacetime. The culture that made them was going through a long period of peace. If they had been at war with other tribes, I doubt very much that they would have attached importance to these works.

The one who made these lines was a high authority or, probably, the boss.
This person was very fond of drawing. He surely spent countless hours drawing in the sand with a branch, or on some surface such as wood, stone or animal skins.
Almost certainly, he had above average intelligence (just slightly above average was enough).

To make these drawings it is necessary to have some notions of Geometry. So the person who made these drawings was what we would call a geometer today. The great Greek geometers of ancient times existed approximately 2,300 years ago. And it is believed that the Nazca culture flourished around the year 200 AD. There is no reason to think that the inhabitants of this part of the world would not have also developed skills in the field of Geometry (in a different way than the Greeks), which would allow them to create these lines.

This person realized that the Nazca terrain was special. Probably accidentally (or simply because he passed by, leaving his footprints on the ground) he noticed, after many months, that the footprints were still there, just as if he had just made them. This area is one of the driest in the world, it is slightly rocky and unlike many other points on the Peruvian coast, the sand does not cover it. Realizing that he could leave an everlasting mark and setting out to make great drawings (similar to the ones he did all the time) was one thing.

Being a high authority or the chief, being in peacetime, not having to earn a living like the other members of the tribe (which left him a lot of free time), with a hobby of drawing that bordered on vice, with subordinates that could help him do any job and with days, weeks or months dedicated to just this activity, it’s no wonder he did.

Ask any friend or family member who really likes to draw, if they think they can do something similar, having rudimentary ropes, many people to help them and all the time in the world and I assure you that the answer will be yes. After all, what we are talking about here is making a small drawing and then calculating distances proportional to a point of origin, point by point. To make a line or straight line in the large drawing, you only need to know the location of its two extreme points, since two points determine a straight line.

But you all may be wondering why they would do something they couldn’t see? If you travel to Nazca, you will see a 10-meter-high viewpoint on the side of the Pan-American highway, and recently another higher viewpoint (20 meters) has been installed.

The inhabitants of that time were able to make a pole, using the trunk of a tree and stop it with the help of ropes and innumerable hands (I have participated in the installation of telecommunication towers 12 meters high and I assure you that it is perfectly possible to reach that height with a log, supported by ropes). At the top, very sure, on a very small platform, was the boss, appreciating and delighting in the work born of his hands and his imagination.
