This is a real Watchtarded belief. If you get on Google, you find that there is enough land to give each person currently living about an acre. Now, that's not arable land. We must assume that Jerkhoober will miraculously make all things new, like transforming Antarctica into a paradise. See Ya later penguins who evolved to live there!!!
The problem is ( OMG, so many problems..) that this does not take into account all of humanity who has lived and died through man's existence. It ONLY accounts for everyone now living.
I suppose Jeehoobster could make the oceans recede and make more land, provide he left enough ocean to serve as a toilet/dump for the untold billions who would be alive for the 1,000 years. Then he can kill off the wicked and start over, or whatever.....
