The Wari and Tiwanaku were the main ones before them. The first civilization in the Americas, the Norte Chico, were also from Peru and were older than Egyptian civilization. And, unlike other cradles of civilization, food crops were not the main source of food for the Norte Chico civilization. Fish was, comprising 90% of their diet. Their main agricultural product was cotton, which they used to make nets to catch fish.They also had precursor civilizations. Forget the names but they had one before them and a precursor to the precursor.
The Inca inherited the Khipu, terraces, and road systems from the Wari. Tiwanaku had chuño and some of the same gods as the Inca. Norte Chico might have had the Staff God that was common throughout the Andes. There are other similarities and influences, too. Lots of Andean cultures did mummification, for example.
We don’t know as much about a lot of these earlier cultures as we do about the Inca.
