"In conclusion, the Olmec people were called Xi. They did not speak a Mixe-Zoque language they spoke a Mande language, which is the substratum language for many Mexican languages.
The Olmec came from Saharan Africa 3200 years ago.They came in boats which are depicted in the Izapa Stela no.5, in twelve migratory waves. These Proto-Olmecs belonged to seven clans which served as the base for the Olmec people."
