I've followed his channel for a year, and I highly recommend starting near the beginning. He builds tools then that are used in later videos. It's fascinating how he's literally building civilization in the forest with only the materials he's found.

EDIT: As an example, right at the beginning of the video, you can see a clay pot and several woven baskets.

Turn on closed captions, he describes a little more as he goes.
