The Round Earth Theory is commonly accepted as fact, so much that it is taught in elementary school and anyone who were to argue this would be told they were wrong and would probably fail to graduate because of their disregard of gravity and physics. So then, why do we round Earthers have to constantly prove that the Earth is round to you? RET is accepted as fact, whereas FET is still a theory, so you should actually be presenting proof to us in order to have your theory presented as a fact. To be fair, we have had space trips, or at least have pretended to, so the only iron proof you could have to force FET to be believed as fact would be to raise money for some kind of satellite, or, at the very least, weather balloon, instead of blatantly disregarding our proof and factual evidence.
So, since suggesting you find indisputable evidence is obviously too much to ask, I want to hear scientific proof that the Earth is flat. If you would please list this proof (not guesswork and bendy light and dark matter, as those are theories and not factual evidence), maybe your theory will gain more respect.
