The document discusses the origins and purposes of cave paintings. It notes that the earliest cave paintings in Europe date back 40,000 years ago in Spain. While the exact purpose is unknown, theories suggest they were not merely decorations but may have been used to communicate or for religious/ceremonial purposes. The first cave paintings were discovered in 1870 in Altamira, Spain and were painted between 16,000-9,000 BC by the Magdalenian people, mainly depicting bisons.
