The Earth is most definitely, provably, scientifically, not flat. If you think it is, then you do not even have a basic understanding of how physics, or the universe works.
Why this is even a question is unfathomable to me. Please go to your local library and ask for a book on what peer review means, as well as maybe how to tell fact from fiction. Not trying to be a jerk here, but this is the most ridiculous thing ever.
