I'm not surprised at all. earth has a rich history of all kinds of life. plus there's still so much about our planet that we don't know about. love seeing new discoveries.

I just watched it and I absolutely love it. The part that got me the most was the animation of the child's burial and the carving on the walls... just absolutely brilliantly astonishing ❤.

One of the most important discoveries in human history and of course doesn’t even make the news.
