The pyramids and temples of Caral, in Peru. Construction possibly began as early as 3500 BC meaning these pre-Incan peoples got the jump on Egypt by half a millennium. The truly remarkable part is that they began their civilization not on agriculture but on seafood which was in rich supply. Pan-Andean traditions such as the love of weaving and fiber and certain deities were established at this very early period, a level of continuity matched only by China. Approx 3300 BC. Artist unknown.
