Believing Their Tiny Island Was the Whole World: The Last Primitive Tribe of the Philippines 

※ This video is part of the program "Primitive Exploration of Humanity - Little Paradise in Caves, Philippines' Tau't Batu Tribe," broadcasted on July 11, 2016.
The Tau't Batu tribe, meaning "people of the rock," continues to live a primitive life inside caves, with about 200 members remaining today. Nestled deep in the jungle of Sigayan Valley, they preserve a Stone Age civilization, hunting and gathering from the natural surroundings near their rock caves to sustain themselves.
While many tribe members have moved their livelihoods to the outside civilized world, the Tau't Batu, the last primitive tribe of the Philippines, still reside in the deep jungle, living as their ancestors did.
