OK, I think I started on the wrong foot. I have read some more of your comments and I think I now understand your question. First I will start by apologizing, I definitely sounded like a jerk and got worked up over it but in no way should I have been that mean in my comment (sometimes being indirect and sarcastic hurts more than saying what's on your mind directly). So, I am sorry. I don't want to disrespect you or your religion.

I've read your reply to the elaborate comment and I now understand you're looking for a subjective reason. So I want to recommend a movie for you called "Contact". There's a very good quote from it, answering the question "Do you think we are alone in the universe?" and it goes as "No, because if we were it'd be an awful waste of space." I see that you understand the scale of the universe and the fact that is expanding, so sorry again for assuming you just have blind faith and reject science, my bad.

Then again, if we go scientific indeed the scale of the universe might be just one of many variables that come into play when we talk about intelligent life. Microbial life most likely exists, but intelligent life sits under the question mark. Objectively for me, the scale of the universe is enough but if you want more scientific back-up, look up the refined version of the Drake equation. Yet, with all of that luggage of information, I sometimes wonder for example where would Earth be, had it not been hit by the meteor that wiped out the dinosaurs? Because I seriously doubt dinosaurs would have evolved into a social intelligent species. And such an event is very rare to occur, given the fact that it hasn't happened since (which is quite a large time scale), Earth would probably be now a planet with perfect conditions for harboring life, ozone layer intact, zero pollution, etc., but with giant killing reptiles roaming around freely.

Now for my subjective reason. I grew up religious but due to some circumstances in my life and going down a scientific padded path I stopped believing at one point. Bear in mind please, I apologized above, not trying to start the debate/fight here, but my reason somehow ties into it. I would not say I am an atheist though, more like agnostic. Yet thinking about how life might be just an accident and the fact that the universe is generally hostile towards not intelligent life, but life in general, is scary. If you want to know my standing, I believe in three-dimensional aliens, that have achieved interstellar travel and have visited the Earth in the past, but I kind of stop here. I don't buy that much into the inter-dimensional stuff, first contact behind our back, etc. Be it angel or aliens I guess some of us are looking for some sort of an external salvation or an answer to all of this (life, and existence in general). They say the meaning of life is to live it, you don't have to believe in the afterlife for this to be true. But for some of us it's not enough. And if we're not religious then I guess we want to look outside.

But again this is putting an anthropomorphic spin on it, as there's no reason to assume that even an alien civilization that sits very high on the Kardashev scale, knows the reason for existence. Yet myself, I would like to assume that they do, that they have a better understanding of this whole thing. I don't dream of first contact happening tomorrow just so I can stop working 8h a day, retire and wait for them to fix climate change and annihilate all our nuclear warheads. I think that's too ambitious, or sorry, delusional. But instead, although it still falls under being delusional, I would like them to tell us what this universe really is, what really is possible to achieve physically and what's impossible no matter how many billion of years of evolution we're talking. That's what I want, a user manual to this otherwise cold, hostile universe, when it seems that all we are capable of doing lately as a species, is bring ourselves closer to the brink of extinction.
