Okay, so go bring back proof.
I want pictures of people touching the firmament.
I want pictures and samples of the sun-ball and moon-ball and whatever stars are.
I want an actual aerial picture of the flat earth. I want pictures of what the bottom looks like.
I want to see what happens when you try to break through the firmament or what effects it has on earthly materials.
Seeing is literally believing. If you can't provide proof, you may as well be saying that the world is the back of a turtle or that Atlas is literally holding it aloft.
