Prehistoric cave paintings are ancient artworks found on the walls of caves, created by early humans during the Paleolithic era. These paintings often depict animals, human figures, and abstract symbols, showcasing the creativity and cultural practices of our ancestors. They are primarily located in regions like Lascaux in France and Altamira in Spain. These artworks are believed to have served various purposes, such as religious rituals, storytelling, or marking territory.
