God... non - existent (sorry if anyone believe in god, personal opinion) Aliens, they have to fucking exist! I mean what the hell. Billions upon billions of planets and nothing else on them but inert gasses and rocks. Not fucking likely. If there is life on other planets they may be more evolved or less evolved but i totally think there is something out there doing what we have done in the past or doing what we will develope in our future. We will eventually meet something...
