Notes from Ancient Astronauts
Imagine you're in a spacecraft in orbit around the planet Earth.
The time dimension in your spacecraft is different compared to Earth's time. A few minutes in your time dimension is one year on Earth.
To adjust and navigate your position and time and space on Earth you make some notes on the planet surface. Lines etched in the ground.

And you choose a mystical place with strong energies that will keep your notes safe for a long period of time, in Earth years.

You make sure that your etched notes are in Sacred geometry images. Resonating with the human subconscious mind. Geometric lines. A bird, spider and some abstract looking patterns.

And when you're busy for fifteen minutes in your spacecraft making an etched note on Earth, the geoglyph will appear in a blink of an eye, in Earth time on the ground, because of the time difference.

And the lines can function as a form of space traffic signs for other crafts to navigate to different places. The people on the surface of the planet will not notice your spacecraft in orbit. They will see a star shining bright in the night sky, as it was always there before. This could be an artistic approach as well. May be Mona Lisa on the moon knew more about this. <...>
What About Time Travelers?
We mean human time travelers, from a distant future, the past or a different timeline.
Etching timeline keyframes in the desert of Peru. Knowing that their lines will last a long time. And eventually they add some new lines. Creating a form of time capsule of symbols and signs. Perhaps some ancient tribes and cultures added some lines as well.

Making it complicated for us to find out what was going on there.

It has happened before in history. The Pyramids in Egypt may be a good example. Created by a very ancient culture. And later on some other cultures added their own elements and removed things from the original design. Could this be the same with the Nazca lines?

Stargate Technology
The lines are old. They stand the sands of time, literally. And the desert is a bit empty.
Was it always like this? So much space. An interesting location for some objects that can have a synergetic alignment with the Nazca lines. A (temporary) stargate or time portal. Perhaps these are objects outside the human perceptions. A stargate hologram. Only to be activated with certain rare Earth minerals. Or de-activated, especially with all those rare Earth metals in cellphones. That's why E.T. used standard kitchen equipment to build his communication device. On the other hand; what does it matter or anti-matter what 21st century technotronics can do, when you have ancient stargate tech that works with Orgone or other exotic strange things.
