Why should the Earth be finite? Why should it have 924,375,700 km circumference? Why not 924,375,600 km or 924,375,800 km? Stop denying the obvious truth of the Infinite Planar Earth.
What you call "Earth" is only our local area, there are many other lands surrounding it, beyond the Ice Wall.
There is PureLand, where humans who are pure enough, through abstaining of drugs (most Round Earthers would be disqualified just by that criterion), drink, gambling or criminal activities, may enter and enjoy a life of felicity.
There is also the land of Structo, where corrupt humans pass on to live a life controlled by a central authority called The Computer. There, no one is free to do anything without approval from the relevant authority. People are conditioned to obey, obey, obey, and forget their own desires, even going so far as to kill their loved ones. It is a living hell filled with paranoia and self-hatred.
Finally, we know about something the Pagans called Summerland, which has a veil that can only be pierced by spirits. Since no one here is a spirit, its composition is as yet unknown.
