We are all in the gutter, but some of us are looking at the stars.

Is Oxygen a "False Positive" for Alien Life?
New research suggests that an exoplanet's atmosphere can contain lots of oxygen — none of it created by life — if bathed in the wrong mix of ultraviolet radiation from its host star.
Fact: free oxygen shouldn't exist in Earth's atmosphere. It's orders of magnitude out of equilibrium with the other gases in the mix. But, thanks to the rise of photosynthetic organisms, its abundance started increasing some 2.2 to 2.4 billion years ago, and (thankfully) it's here to stay.
"Space is big. Really big. You just won't believe how vastly, hugely, mind-boggingly big it is. I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space." - The Hitch-Hikers Guide to the Galaxy - Douglas Adams 1952 - 2001
Earth is a big asylum constantly taking in newcomers.

Hopefully...its here to stay.
In an ideal World a law would be passed were NO guns were allowed and all those out there destroyed, trouble is the law makers are not going to take a risk of trying to pass that without making sure they are armed first.
