The Olmecs are a mysterious culture considered by many as the Mother Civilization of Mesoamerica. Archaeological sources believe their civilization began around 1250 BC. However, there are also opinions that it is much older, and its origins date back to 3113 BC, when god Quetzalcoatl arrived to the region. While others suggest the Olmecs originally came from Africa and introduced a calendar, writing, pyramid and tomb construction, mummification, and religious traditions to the native Americans.548513d08dea5117d8ec00a5014f25c5-OMLEC
