Extraterrestrial coming-out in my little voting concerning you regional background: well, I'd like to comment on that one a little bit.
Whoever you are, most likely you didn't vote from up on the space station in Earth orbit, rather I'd guess you did vote from out of an airplane. (It does not come to my mind that you might not have told the truth. No, this possibility doesn't pop up. Why should one?)
But just in case that you actually are from Alpha Centauri: don't bother with our planet. We're doing away with it as soon as we can; I'd be very thankful if you just could patiently wait until we're done with our self-destruction mechanism, I might not even report you to the authorities.
You can have our planet soon, in a few hundred years it might be free of our species. Well, yes, there might, then, be some work to do to make it inhabitable again, but what is this to you if you're able to travel so far?
So, please, leave us alone for the time being, at least until I am gone. What may happen after I'm dead is none of my concern: that is just how we humans are made - we simply do not care very much about anything that may happen after our lifespan is discontinued.
You may have to fight for this world if you want it know, but if you wait, it will be presented to you for free. Now that's an offer, isn't it?
