It goes beyond a lack of scientific knowledge. To be a flat Earther, you also need to believe there is a vast conspiracy to cover up the fact that the Earth is flat. NASA and other countries' space agencies, astronauts, pilots, astrophysicists, geologists, meteorologists, and anyone whose job requires taking into consideration the spherical nature of the Earth (so: GPS systems engineers, flight guidance software programmers, ballistic weapons systems engineers and operators, and I'm sure many more). They're all in on it for... some reason? They somehow stand to gain from tricking the sheeple into believing the Earth is a globe? And none of these conspirators have defected and blown the whole thing wide open? It's not like there is roughly equally compelling evidence on both sides and these people just lack the mental tools to determine what is right. People become flat Earthers for the same reasons I believe people fall for many conspiracy theories: it's nice to feel special because you see the truth everyone else is blind to, and it's exciting to think there is a big conspiracy happening for who knows what end.
