Hello
I agree that merely believing what others say isn't a good belief, but considering Earth flat is a belief as well. I was wondering about your idea of Earth being flat, so where the edge is? How is Earth, round, square, shaped as a diamond? Do you fall if you walk beyond it? where do these edges end? In the middle of the Pacific? Who took the What's on the other of it (being upside down)? and finally, how do you know this? Do you just believe in what others have told you?
Is this some sort of joke on us? 8-)
