If you don't know the answer, what makes
you think there is one? In order to believe in a theory, you must be guided by evidence. How did you
personally come to believe the Earth is flat? Please don't give me a bunch of garbage like links to flawed experiments or your common phrase of "look out your window".

In other words, how did you manage to not get brainwashed and learn the 'truth'?
P.S. This isn't an invitation to ignore my previous post.
