For generations, archaeologists, historians, and romantics alike have gazed at the petroglyphs and pictographs of ancient peoples and declared them portals into mysticism. Every line and circle, we’re told, was a cosmic vision, a shamanic trance, a plea to the gods. The narrative is irresistible: ancient peoples as spiritual savants, forever painting their stone scriptures to commune with unseen worlds.

But what if this is mostly wrong? What if the majority of rock art wasn’t mystical at all? What if it was practical communication—an early human billboard system designed to tell people where to go, what to do, and how to survive?

Human Communication Is Overwhelmingly Practical

Start with a simple truth: modern humans are still anatomically and cognitively the same as those who carved the caves of Lascaux or chiseled deer into sandstone. And when we look at ourselves, the overwhelming majority of our communication is not religious, not artistic, not profound.

Most of what fills our environment is practical:

• Directional: traffic signs, GPS prompts, trail markers.
• Transactional: receipts, contracts, text messages.
• Instructional: warning labels, “push/pull” signs, airplane safety cards.

Even in an age of art, memes, and spiritual exploration, the vast bulk of what humans produce is utilitarian. It stretches logic to assume that prehistoric humans were fundamentally different—that they ignored practicality to produce nothing but spiritual visions.

Rock Art as Information Technology

Seen through this lens, rock art stops being a mystical code and starts looking like early information technology.

• Wayfinding and Geography
  Many rock art sites align with choke points, passes, or water sources. These weren’t random canvases—they were public notice boards at high-traffic places. A circle within a circle may have been a “spring ahead” marker.
• Resource Calendars
  Animal depictions may correspond to migrations or seasonal abundance. What archaeologists label “ritual hunts” could equally be annual reminders: “This is when the herds come.”
• Territorial Markers
  Carvings could serve as early signs of boundary and ownership: “This is our valley,” or “Danger lies ahead.”
• Instructional Diagrams
  Stylized figures may have taught hunting strategies, group formations, or even safe passage routes—visual mnemonics for a largely oral culture.

In short, the art worked the same way a modern trail map or highway sign does: by condensing survival knowledge into durable, shareable symbols.

Why We Keep Calling It Religious

So why the obsession with mysticism? Because it makes the past feel exotic. It’s more exciting to imagine shamans in trance states scratching cosmic visions than to imagine parents carving warnings for their children about where not to drink the water.

There’s also the Western bias: modern scholars split “the sacred” and “the practical” as separate categories. But for many Indigenous peoples—past and present—there is no hard line. A hunting reminder might also be an invocation for luck. A map to a spring might also honor the spirit that dwells there. The spiritual and the practical overlapped.

But overlap doesn’t erase primacy. The survival message comes first; the prayer comes second.

Romanticism Infantilizes the Ancients

By insisting on mystical explanations, we infantilize ancient people. We turn them into one-dimensional shamans instead of resourceful humans navigating hard landscapes. We make them dreamers when they were, above all else, doers.

The people who carved deer into stone weren’t doodling visions for us. They were leaving clear signals for their peers. To call those signals “cosmic” is to strip them of their humanity and practicality.

The Likely Truth

Rock art wasn’t humanity’s first Bible. It was humanity’s first bulletin board.

It was the survival manual etched in stone, the public signage system of a world without paper or cell towers. It was both practical and, at times, sacred—but the practical use dominated.

And why wouldn’t it? Humans across time, across geography, across culture are remarkably similar. Most of our words today are informational. The simplest, most human assumption is that theirs were too.

Stop Mystifying, Start Understanding

Instead of treating every spiral as a cosmic vortex, we might better honor our ancestors by seeing them clearly: as people who cared enough to leave behind practical notes for each other. They were planners, coordinators, and teachers. They carved because communication mattered.

Rock art is proof not of their mysticism but of their humanity—practical, pragmatic, and enduring.
