I agree that just looking at the night sky, you can tell that there's probably like somewhere else out there.
Now why haven't we seen it? Well they could be really really far away and by the same token they haven't seen us. There's technology and there's interstellar technology in science fiction. We don't have it either, so... Maybe there's a civilization forming somewhere reasonably close and by the time they're beyond burning stuff there are no more of us.
I'm not sure about the fossil fuels theory.
I don't get the longing for the contact with aliens thing. It's really fun and exciting in fiction but probably won't be so great in reality. Either we're dominating them or they're dominating us. OR: they're so so advanced that they're ultra pacifists and they come to the decision that the best thing for earth would be to exterminate most of the human race, just leaving a few vegans.
[Bonus points if anyone recognizes the series I'm referring to. It was kind of interesting, but I felt like the main character was a traitor to the human race and it made me want to be all HUMANS ARE SUPERIOR!!!]

I just read an article where it was postulated that one third of Sun-like stars host warm, water-bearing planets. Using the Milky Way as the obvious example, a minimum estimate of 200 billion stars of which 7.6% are G-classified (our Sun is a G) yields 15 billion stars with potentially Earth-like planets. At 13 billion years old, I find it inconceivable that there isn't intelligent life elsewhere in the galaxy.
Jump to Fox's new Terra Nova TV show, and more relevently the discussion on the TV/Movies board. Living on a planet without fossil fuels means that the only way to extract energy is to burn things, turn a water/wind mill, etc. until you're able to refine fissionable or create solar panels.
Taken together, I have to wonder if one reason we haven't seen other intelligent life already is because the energy available to make the transition from low-tech energy sources to anything more capable is precluded by the necessity for fossil fuels to serve as an intermediary energy source.
Think about it: how likely is heavy industry - metallurgy in particular - and the following technological society to even be possible if the best you can do is lighting a wood fire?

An interesting thought I had that may be worth discussion.

Well just look at the history of Earth. And the cultural/advancement disparity would be FAR greater. *NM*

In one particular space opera, it's a mix and probably the best situation possible for humans.

Unless their advancement is so great they are VERY ethically enlightened, her fears seem valid.

Yeah but that's just a variant of "Highly advanced aliens who for some reason are totally stupid"

Re: If life formed, why might there not be fossil fuels equivalent to, or greater than, our own? *NM*
