I was actually pretty surprised when I learned how many people actually believed that the earth was flat. I thought it was only a joke made by internet trolls and maybe a few cases of individuals trying to sell books to gullible people. Its shocking that we are actually taking steps backwards in our progression of knowledge in today's time. I mean, we now have an actual flat earth movement and people are going as far as refuting natural laws like gravity so that they can maintain this idea that there is a large scale global conspiracy that's trying to convince the world that the shape of the earth is a sphere...
It would be funny if it weren't so scary how easy it is to shape some minds.
