8. Mars Attacks!(?)
That’s really just typical. Every movie always talks about Martians invading us with their killer robots and fancy plasma guns, but if there is life on the Red Planet, we may have beaten them to the punch. Indeed, how many probes and robots have we sent to explore so far?

On the bright side, we have at least went mostly to explore, and not to invade (or so they tell us). Still, I’m going to prepare for round two myself by making sure to have a fully stocked cellar for the counterattack. Just to be safe.
