Petroglyphs are ancient rock carvings created by people to express their thoughts, beliefs, and experiences. These images are made by chipping away the surface of rocks, revealing lighter stone underneath. Found in various parts of the world, petroglyphs often depict animals, human figures, and symbols that hold cultural significance. They provide valuable insights into the lives of early civilizations and their connection to nature. Many petroglyphs can be seen in places like North America, South America, and Europe. Each site tells a unique story, reflecting the traditions and values of the people who created them. Today, these carvings are important archaeological artifacts that help us understand our shared human history.
