The oldest known civilization in the Americas is the Caral-Supe civilization, which flourished in what is now Peru around 3000 BC. This ancient civilization is notable for its impressive architectural structures, including pyramids and urban centers, all built without the wheel or writing. The Caral-Supe people engaged in agriculture, fishing, and trade, contributing to their societal development. Excavations have revealed complex social structures, religious practices, and evidence of advanced agricultural techniques. Understanding this civilization has provided significant insights into early urbanization and cultural development in the Americas.
