the fact that you believe that gravity doesnt exist/earth is flat/etc is sorta irrelevant - its more the fact that you just shut your ears towards anyone suggesting anything different than what you believe, let alone look at any proof to the contrary, or actually acknowledge lack of understanding of a concept or piece of evidence
do you actually expect to be able to see a satellite with the naked eye, or even a telescope? have you ever been to a mountain or somewhere high up and attempt to see people in a town or building down below?
if you cant accept what other people show you that goes against your views, how can you expect to work a real job where you dont have hands on everything and depend on others to get you information?
