I'm not to scared of any aliens. I mean, I do believe in them, but why would they be interested in us is beyond me? Humans seem to love to believe that we're special and important xD, u know like aliens want to use us cause they need us to survive, or they want to enslave us or want our nuclear weapons. My theory is, if aliens exist somewhere (and i do believe they do, maybe not anywhere close by but come on, if life can form here it can somewhere else too!) and if they ARE able to travel to earth, then they've probably already checked us out and left. I mean if they can travel to earth they have technology beyond ours and got everything all sorted out pretty much. If they can travel anywhere they wanna go, i doubt they're gonna want our polluted and corrupt little planet.

so basically with that theory, there's nothing to be scared of!
