Comment Looking for life in all the wrong places (Score 1) 335
It amazes me that you can't concieve of the possibility that this is the first planet in the galaxy for life to have formed.
While it is technically possible, it seems astronomically unlikely considering the size and age of this galaxy. Our sun is not even a first generation star. First life in the galaxy should have occurred billions of years before our solar system even formed.
We haven't found any evidence of it anywhere else, and it's not from lack of looking.
It most certainly is from lack of looking. So far in all of human history, all we have done is a decent (not perfect) job of looking on the moon, and made a half-assed attempt at checking a few square feet of mars (if it was teeming with life we wouldn't have missed it, but we hardly checked exhaustively). 99.99999.... % of the galaxy is still left completely unexplored. We don't have enough data to even think about making conclusions about the prevalence of life in our own solar system, let alone the rest of the galaxy.
Titan and Europa are good candidates. If we don't find any there, we may not find any anywhere.
Yes, they are good candidates for carbon-based "life like us". Given the spectroscopy results of Titan's atmosphere, I would actually be surprised if we didn't find at least simple bacteria-like life there.
However, I am certain there is more than one basic path to "life" in this universe (even in this galaxy). We arrogantly assume that other life must function in a similar manner to us, so we only bother to even consider looking in environments vaguely similar to ours for life vaguely similar to us. There may well be life on Venus, or even Mercury, or the surface of the sun, or hanging out in the Oort cloud (just not anything remotely similar to Earth life). Even our science fiction does a piss-poor job of exploring this concept.
