You have to spell out the persons make to make them leave. Or at least give most of their username. "everyone insulted me" is pretty vague and general. I won't be leaving on that.
Like I said before gravity and wind disprove your argument, plus if the world is flat what is on the other side?
If the world is flat, name 1 person who has fallen off the Earth. And explain how Magellan, the man who sailed across the world, did what he did, if our planet was flat.
