The settlement is right at the border of what would be controlled by the Inca government, two millenniums later. It shows that there’s some decent access to the region from the west than you’d be led to believe, with the Andes in the way.
As such, if they find other cities further east, I’m predicting that, culturally speaking, they’ll resemble nothing this one; even if they happen to be roughly the same size.
People ate maize and sweet potato, and probably drank “chicha”, a type of sweet beer.
“If you don’t have chicha, any small thing will do.” (reference to a certain song)
Serious now. Potentially yucca too - it grows right next door, and if they got maize from North America then they likely traded for crops.
