Alright, so you think that the earth is flat. You don't believe that satellite photos are real, and that's fine. But what I'm asking is what will actually prove to you that the Earth is round?

The earth might actually be flat, although unlikely, and I probably have more knowledge about this than the average person (not to say I'm an expert or anything), so I'm not going to rule that out of the table. No matter what evidence exists, whether it be the fact that I can fly from Europe to America via the Atlantic, or loop around the world by going past Asia, or that photos have been taken of planet Earth itself in a round form and never in a flat form, you seem to think that everything is fake. So I ask you this: What does science need to provide you to convert you into thinking the earth is roughly spherical? (Not exactly, but it's close enough). I saw a good video a while ago about why conspiracy theories are flawed, and the verdict was that all conspiracy theorists say that all evidence against the theory is fake, which is why I ask this.
