What's your reasoning behind that? Every sci-fi movie you've ever seen? Please, the chances of a "Shoot first, ask questions later" alien race aren't that likely in my eyes. I could imagine an alien race that strides for diplomatic and peaceful contact first rather than obliterate the human race.
As for me, yes, I do believe in aliens, in fact, it's quite hard to believe that our planet is the only one in the entire galaxy, let alone all of space, that can support life. However I think that either they don't want to waste their time with a race that is going to wipe itself out or they're sitting back and watching the show.
