Are you guys crazy? You read some books, you notice some releations and begin speaking of doom? Why? An apocalypse is a visual representation of cleansing.
Self-discovery, cleansing and balancing.
There wont be any zombie apocalypse or anything else that paranoid delusional people seem to think. Ive met many of them.
Furthermore, the earth is round. If you want a flat earth, go make one yourself, but leave ours alone.
