I believe we live on a globe.
No wait, scratch that. I KNOW we live on a globe.
What would change my mind? A number of things
1. Traveling anywhere in the southern hemisphere and seeing the star Polaris
2. Traveling anywhere else in the world and seeing a part of the moon that is not visible from where I am, as would have to happen on a flat earth model
3. NASA coming out and admitting it
4. Seeing the "southern ice wall", possibly guarded by penguins (with machine guns??)
5. A friend travels to Antarctica and never is seen again...
To me there is little solid, rational evidence to prove the earth is flat. The Earth has already been PROVEN to be round, so the burden of proof is on those who say the earth is flat.
So far the only explainations I've seen have been similar to "I don't see a curve" or "I walked around a bit with a level and it didn't change therefor the earth is flat". For whatever reason no FEers have been able to explain why we all see the same face of the moon, why travels from Asia to North america don't go over the north pole or instead take an absurdly long route that would take several days to complete, why only some stars are visible from certain places, why stars move across the sky in different directions depending on where you are, and why people are able to live and work in antarctica, travel to the south pole, and not run into an ice wall.
So currently, there are just too many problems with the FE model to be plausible, and little scientific evidence to support it. And by scientific evidence, I mean done by actual scientists, not some random pleb on the internet that hasn't gone to college or likely even high school, thinking that holding a glass of water to the horizon proves a flat earth.
