Many UFO researchers believe that ancient rock art could be evidence that ancient astronauts visited Earth.

Two men in mysterious cryptic drawings found in Italy show them wearing helmets with unusual weapons. It is possible that they are ancient astronauts who arrived on Earth.

Petroglyphs seem to depict strange characters in protective suits. However, white lines also appear from the heads. Some believe it might be the helmets’ lights. The drawings at Valcamonica, near the central Alps in northern Italy, are believed to be 10,000 years old and are part of a collection of more than 200,000 petroglyphs carved from the valley’s rocks.

While most of the drawings depict symbols and animals, some are notable for their bizarre nature, such as these old astronaut drawings. “Believers of ancient alien theories point to these rock carvings as evidence of prehistoric alien visits to the land and claim that the drawings were made by local people recording what they were witnessing at the time.”

In 1979, the collection of petroglyphs was recognized by UNESCO as a World Heritage Site – the first in Italy. Conspiracy theories believe that aliens are present throughout human history. They claim that aliens have guided humanity’s evolution.

They point out things such as the mystery surrounding the building of the pyramids, and other rock drawings, as evidence that aliens arrived on Earth to help our ancestors.

Robert Bigelow (CEO of Bigelow Aerospace), is a space entrepreneur who believes aliens have visited Earth. He recently said to CBS: “I am convinced that the aliens have visited us. An alien presence existed, and it is still present.
