Ancient Astronauts or Psychedelic Visions?

At Tassili n'Ajjer in the Algerian Sahara, a 7,000-year-old figure walks the rock face with mushrooms sprouting from its body and a strange bulb of a head. In the Pegtymel petroglyphs of Chukotka, similar mushroom-headed beings dance. The Selva Pascuala mural in Spain, dated to roughly 4,000 BCE, shows a row of small Psilocybe hispanica fruiting bodies — the oldest known depiction of magic mushrooms in Europe.

Popularized by Erich von Däniken in Chariots of the Gods? (1968) and decades later by the Ancient Aliens television franchise, the easy reading was that the figures depicted literal sky-people landing in literal helmets. Across the globe, every culture seemed to be drawing the same beings.

The simpler explanation

Anthropologists and ethnobotanists like Jeremy Narby and Terence McKenna offered a different reading. Every culture was drawing the same beings because every culture was, in some way, using the same chemistry. The mushroom-haloed shaman with the impossible head was not an alien — it was the vision itself, painted onto rock by someone who had no other vocabulary for what they had just seen. The 'sky gods' were inner gods. The starship was the human nervous system.

“The shamans had no word for hallucination, so they painted what they saw — and what they saw was very strange.”

Two doors, same room

The two theories are usually presented as rivals. They may not be. If the McKennas of the world are right about DMT entities, and the panspermia people are right about spores, then the cave painters were doing exactly what cave painters do: faithfully reporting an encounter. Whether the figure on the rock came from a starship, from a mushroom, or from the human brain depends on which corner of the cave you happen to be sitting in.
