Breh let this die, there is absolutely nothing you can do to convince people who have their mind made up. Like you said, for some reason the burden of proof is on on you, like you're supposed to know centuries of science by heart. But Earth-flatters somehow don't have to prove anything, they say "we're just asking questions" lol...very handy. Whatever proof you provide they will question the source, say it's a conspiracy, etc. There is absolutely NOTHING you can tell them that will change their belief, even if you gather
45000 scientists of all countries they will just say it' a global conspiracy and that you're sheep
