The guy who discovered coffee is said to be an Ethiopian goat herder named Kaldi. He noticed his goats dancing energetically after they consumed the beans of a coffee plant, which grew wild there at the time. After trying them himself, there was no turning back. You can see a real history of coffee in a previous video.
Ryan George, on the other hand, retells the story from the perspective of a guy who will try anything, and that includes boiling beans and drinking the resulting sludge. In this scenario, he is the first person to ever do so. His friend cannot believe the stupidity of this act, until he tries some coffee himself. The video is caffeinated, so it goes pretty fast and is only two and half minutes long. The rest is an ad. The moral of the story is, don't drink brown water unless someone else has already done it and survived.
