Sometimes is best to speak to spinning ball earth believers in memes.
Look Astargath, these I pick for you. Maybe you will start thinking:
And look here, your monkeyman science priest is telling you the truth (Sometimes this liars I believe, are unwillingly forced to speak out a bit of truth)
The only three "proofs" spinning ball earth believers have, are:
1.Nasa images ("It is photoshopped, but,but... its has to be" - Robert Simmons, nasa artist).
2.Public indoctrination (We know, because monkeyman scientist said so).
3.Opinion of the masses (Many are believing, so it must be true).
