Actually the idea of a spherical earth was from Phytagoras and then Aristoteles confirmed it. Are you guys saying the ancient greeks used to spread fake news with non-yet-existent mass media?

The basic approach of science is to not take anything for granted and scientists keep trying to prove themselves wrong all the time to understand if their theories really make sense. So what reason they could possibly have to lie?

Mass media and big corporations are not science, they're institutions. On this point I do agree, institution often pursue they're own interests for money. But again, science is not an institution, it's a useful method to figure out how our reality works.

and seriously, if the Earth is flat where is the edge of the world and how do you explain round shaped eclipses? 0.0
