Indiffernt. Until a UFO turns up in my garden and aliens come out of it, I'm not really fussed.
Seconded, I don't 'beleive' in aliens. They might be there, they might not be. Chances are there are other planets with life, but untill there is solid proof I won't draw any conclusions. I hope they exist though, o yes I hope this galaxy is buzzing with life and activity.

I don't. The requirement for life as we know it is incredibly huge. In the trillions of stars we've discovered, we've only discovered 11 planets outside of our own solar system, meaning to me that planets are few and far between.
11? Sorry my friend, the counter is on 346 planets [http://exoplanet.eu/catalog.php], not 11. Planets are actually pretty abundant, and far from far and few between. Also keep in mind that we've only just begun looking for them. We found our first planet in 1995, only 13 years later we can already add 345 planets to that. And only recently we've started with serious missions to look for (especially terrestial) exoplanets. In 2006 the ESA launched COROT [http://en.wikipedia.org/wiki/COROT] and last month NASA launched the Kepler Mission [http://en.wikipedia.org/wiki/Kepler_Mission]. There are obviously more missions planned to look for planets and even life [http://en.wikipedia.org/wiki/Darwin_(ESA)] on other planets. SETI is hopelessly outdated ;-)
Edit: We've even found a planet within the "Goldilocks zone" already [http://en.wikipedia.org/wiki/Gliese_581_d]:
On 21 April 2009, ESO announced, together with the discovery of Gliese 581 e, that they had refined the models of Gliese 581 d's orbit, discovering it lay well within the habitable zone.
And we've barely even started looking, ain't that awesome?
We also know that we need sufficient quantities of all sorts of elements. But that's not all: I also think it's hard to believe because of how unbelievably random of an occurrance life forms under.
If there's any reason to believe in Creation, it's the fact that the odds of any life ever occurring on its own are one in almost infinity. We've actually tried many, many, many times to create life from everyday elements, but it just doesn't happen that easily. For life to exist, you need to have atoms and molecules that actually want to survive. How hard is that to process?
Odds are not important, since chemistry is (far from) all chance and randomness. Put 2 chemicals next to eachother in certain conditions, a reaction will occur. Put the same 2 chemicals next to eachother in the same conditions as before, the same reaction will occur. Saying that life needs atoms and moleculs to 'want to survive' is...odd, how can they survive, they're not alive. They just exist under certain circumstances. And I doubt the quantity of elements will be a problem, we've even found amino acids in interstellar space [http://www.space.com/scienceastronomy/generalscience/amino_acids_020327.html]. Now if that's not enough, I don't know what is ;-)
