It amazes me. Why you are so closed minded guys? Why not cubic earth?
The earth is also cubic.and also diagonal and also ceiling and of course infinite landmass even within our boundaries.
An "infinite" land mass with "boundaries"...that is the smartest thing I have heard anyone say about anything ever..so sexy 
You think in one dimension and even in this dimension the earth is infinite.
You can't have something infinite with boundaries...it does not compute, hence the snarky comment earlier.
And stop speaking flat earth assumptions, the typical "you are scared, think inside the box not out side, shill, cognitive dissonance etc etc etc..."
So don't speak for my thoughts, I believe in at least 10 dimensions which is why I am a proponent of string theory, it also adds to my faith in Yahweh. So stop assuming, it makes an ass out of u and m
