If you don't mind, I'd also like to add one that I have not seen answered anywhere on this site:
The Southern Cross
I live in the Southern Hemisphere...to the south, at night, I always see the collection of stars known as the southern cross. And by south, I mean the direction that is opposite to North. I have visited Australia, and Chile during my time on this lovely flat earth and I see the Southern Cross sitting toward the south, albeit at somewhat different angles.
Funnily enough, in the standard flat earth model, this isn't possible. It would mean that the cross is in every single direction all at the same time.
I brought this argument up once, and the ONLY answer that was given was: "Warping of space"
That is what constitutes an "answer" on this site. So don't expect too much substance in any responses you get, friend.
