Of course if there is alien life in the universe, you're a naive c*nt if you think otherwise, it's only a matter of time before we have proof.
The real question is, is there intelligent life out there? Or did there used to be but it has now been wiped out? Or maybe it'll be millions of years before another intelligent civilization appears?
Think of it this way, the Universe is 14 billion years old (estimation), and the human race is only 10000 years old, and most likely won't see another 10000.
Maybe there are lots of intelligent life but they die out quickly
