The trace was left by aliens. The meaning of the pictogram: people of Earth, it’s time you became wiser and stopped evil on the planet; otherwise the planet will die. In the big circle there are faces of aliens. In the small circle there are faces of people. The white line is the energies being sent into the mind of earthlings with the purpose of teaching them. Near the circle with human faces there are two small white circles, two signs which means destruction. Near the circle with the faces of aliens there are three signs on a curve (the path of the negative) that show that evil must be stopped. Below the line there are two short lines, which means the death of the planet (the number 2 symbolizes death). The negative will lead to destruction. The same information is shown above.
