who built the first known civilization in the americas
History of the Americas In the late Archaic, on the north-central coastal region of Peru, a complex civilization arose which has been termed the Norte Chico civilization, also known as Caral-Supe. It is the oldest known civilization in the Americas and one of the five sites where civilization originated independently and indigenously in the ancient world, flourishing between the 30th and 18th centuries BC. It pre-dated the Mesoamerican Olmec civilization by nearly two millennia. It was contemporaneous with the Egypt following the unification of its kingdom under Narmer and the emergence of the first Egyptian hieroglyphics.

Continent In 1501, Amerigo Vespucci and Gonçalo Coelho attempted to sail around what they considered the southern end of the Asian mainland into the Indian Ocean, passing through Fernando de Noronha. After reaching the coast of Brazil, they sailed a long way further south along the coast of South America, confirming that this was a land of continental proportions and that it also extended much further south than Asia was known to.[48] On return to Europe, an account of the voyage, called Mundus Novus ("New World"), was published under Vespucci's name in 1502 or 1503,[49] although it seems that it had additions or alterations by another writer.[50] Regardless of who penned the words, Mundus Novus credited Vespucci with saying, "I have discovered a continent in those southern regions that is inhabited by more numerous people and animals than our Europe, or Asia or Africa",[51] the first known explicit identification of part of the Americas as a continent like the other three.
