Rock engravings are images or symbols carved into rock surfaces, often created by ancient cultures. These engravings can depict animals, human figures, or abstract designs and are found in various locations around the world. They serve as a form of communication and expression, providing insight into the beliefs and daily lives of the people who created them. The process of making rock engravings typically involves using tools to scrape or chisel away the rock surface. Many of these engravings are associated with archaeological sites and are studied by researchers to understand the history of human activity. Notable examples include the Petroglyph National Monument in the United States and the Bhimbetka rock shelters in India.
