Pre-Columbian era
The earliest known civilization is the Olmec. This civilization established the cultural blueprint by which all succeeding indigenous civilizations would follow in Mexico. Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near the coast in southeast Veracruz. The Olmec influence extended across Mexico, into Central America, and along the Gulf of Mexico. They transformed many peoples' thinking toward a new way of government, pyramid-temples, writing, astronomy, art, mathematics, economics, and religion. Their achievements paved the way for the Maya civilization and the civilizations in central Mexico.
South America
One of the earliest known South American civilizations was at Norte Chico, on the central Peruvian coast. Though a pre-ceramic culture, the monumental architecture of Norte Chico is contemporaneous with the pyramids of Ancient Egypt. Norte Chico governing class established a trade network and developed agriculture then followed by Chavín by 900 BC, according to some estimates and archaeological finds. Artifacts were found at a site called Chavín de Huantar in modern Peru at an elevation of 3,177 meters. Chavín civilization spanned 900 BC to 300 BC.
