Hundreds of ancient geoglyphs in the Amazon hint at complex societies. Archaeologists uncovered nearly 400 circles, squares, and other geometric shapes carved beneath the forest canopy using laser technology. The geoglyphs are estimated to be roughly 1,200 to 2,600 years old, challenging the long-held theory that the Amazon was largely untouched before Europeans arrived in the 15th century. Researchers think the carvings were used for festivities among an ancient society called the Aquiry.
