No legit flat earther believes that we are on some sort of disc floating in a space void/vacuum, or able to fall off an edge. That's "Flat Earth Society" bs.
It is not "pointless" to try and prove the actual variables in an equation. "Thousands of scientists", even those whom are "Peer Reviewed" can be wrong. Without a way to measure the distance with a laser, radio signal, etc, then all you have is a theory.
So if you really want to engage in this conversation, I implore you to give me one single proof of the distance, using the Scientific Method.
If you live in Australia and I live in Argentina, can you point a laser or shoot a radio signal at me and tell me the size and distance from you of the ball that I am holding up?
