My experience with you types is that you hardly know anything, and certainly do not understand geography or science. We have known for centuries that the Earth (and other planets) are round, and why that is. The proofs are the circumnavigations and cartography possible only on a round world, not to mention spaceflight in orbit and deep space photography of the spherical Earth. Instead of learning about it, you guys get invested in a social delusion where you have to believe that EVERYONE is lying to you about a huge HOAX---presumably being put on for your special attention. Why you would matter to anyone is a puzzle, but---hey!---it gives you prestige to think you are so special, someone is hiding a secret from you. A secret that only you know! Except...except you have no evidence whatsoever. All you have are "questions" and arm-waving videos (to spare you the effort of writing anything down in cogent form).

If the Earth is flat (which it isn't), a proponent of that hypothesis should be able to point out a crucial factual proof in a few sentences. No one has. It's all supercilious posturing and "Hey, this video explains it all."
