"Well, just because we don't have endless hordes rushing at us from the Chaotic Evil afterlife doesn't mean we'd like to all pathetically roll over and die if someday we did get invaded, though usually we'd suppose them to be invading with machines or cleverness.  So we try to prepare ourselves, rehearse for it, just in case.  Some of the best writers and the best just-in-case military people and maybe some Keepers I don't know all get together and plan out how they would invade us if they were aliens with particular capabilities, and then during the Alien Invasion Rehearsal Festival they get to tell us, this city got wiped out, or everybody in this region just got mind-controlled, or whatever, and then everybody in the region who got mind-controlled will pick up whatever pretend weapons they get issued and try to come pretend kill the rest of us.  And, I mean, that also increases resilience if someplace gets hit by an earthquake, because people know who to cooperate with and which houses to check and how to look for bodies before their brains rot, that sort of thing.  But running it as an Alien Invasion Rehearsal Festival instead is more fun."
