Groups in the Amazon rainforest?

Explanation: There are still vast areas in the Amazon that have yet to actually be explored/discovered. In fact, every couple years, a new tribe is discovered. There will be a logging company and they will cut down some trees and all of a sudden, there's like a village and the people that live there have never seen anybody else ever in their entire unexcited. So they're untouched and undiscovered people.
