Firstly, I'd like to mention that most Flat Earthers (those of us who believe in the Flat Earth) are atheists as well, and the Flat Earth Theory has no correlation to Christianity, any other religion, nor religion in general. I'm not sure if you were implying otherwise in the beginning of your post, but just to clarify all of that in case you were.
As for your questions: Yes, and yes. I'd be very surprised if it contradicted my beliefs, but yes, I would definitely see if I could get over to the ice wall or into space if it were possible.
I'm nearly positive that most everyone here would concur with that response as well, seeing as the Flat Earth Theory is a zetetic theory, based on facts and true results, rather than preconceived biases.
