Last week I posted a video about how we know the Earth is round, from the perspective of modern astronomy. The Flat Earth community did not like it one bit, and the channel "Globebusters" decided to talk for three hours on their livestream about how stupid my video is, and how stupid I am. I didn't really appreciate that, so I decided to make a video about their video to illustrate precisely how little they know about science, and to further reinforce how utterly absurd the Flat Earth "model" is, as well as some of the finer points about the conspiracy. Enjoy!
