I said it before and I will say it again, FE biggest problem is the idea of edge. It is extremely difficult to imagine any edge to our earth and it seems physically impossible for a planet to be flat with edges from which you can just fall into deep space. Infinite flat earth model is the only flat earth model that works. The video that was posted here earlier is very good. However there is no edge, the earth continues on forever and not forever cold and sunless, just over the ice wall are more continents and more suns, paradise lands, endless beauty.
