Who invented petroglyphs?

Petroglyphs were not invented by a single individual; rather, they are ancient rock carvings created by various prehistoric cultures around the world. These artworks date back to the Upper Paleolithic period, with some of the earliest examples found in places like Europe, Africa, and Asia. Different indigenous groups, including Native Americans and Aboriginal Australians, developed their own styles and purposes for petroglyphs, reflecting their cultures, beliefs, and environments.
