I don't know man, I was being a bit dramatic, and I was a bit drunk.

but essentially, if you are like really serious about this, that you really do believe that the earth is flat, how do you explain mountains? something can only be flat if it is in a 2-dimensional plane. 

reminds me of this book called flatland. it's about a square who meets a sphere and is shown the 3-dimensional world,  

what I am getting at is that, either:
1) you are just fucking with people, being on the fringe, being "edgy" 
in which case stop being so damn edgy. the kids will believe most things.
or 
2) you mind cannot grasp a conceptual notion that there is something other than our earth, it is a very narcissistic world view, that leads to more ignorance, and possibly hatred for anything that challenges your worldview.

in history, people did A BUNCH OF SHIT (science math and what not) and they did not have much else to do but that kind of stuff. and they were dead set on that their evidence based on their methods of inquiry known today as the SCIENTIFIC METHOD. which to paraphrase the shit out of it into something I hope to you understand is that. 

you do shit to disprove anything that is held to be in question. 

so a conversation might go as follows in a scientist's mind:
"hmm Jeffery said that the weight of my football would cause it to sink if I were to put it into water, this being because he says that the football is heavier than water and so would sink. I think that it would float though." he sits there and tries to DISPROVE that his theory, that the ball would float, is wrong. so as to either confirm or deny the value of his friend's theory. 

it essentially boils down to that.  basic science. 

and a good scientest tests their theories multiple times, and then they tell others and then they test it and see if they get the same results.

and there a shitton of people that undeniable proof that the world is indeed, a three-dimensional object known as a globe, (spheres like circles are perfectly round so that is why a globe is like a sphere but is not one, has to do with pi.)

i hope i did not give information overload, but please lets discuss this. i enjoy such things as this. makes me feel all smarticles.
