Mars is the best candidate for life that is easily reachable. Yes, Titan
and Europa are good candidates as well but pretty much every month NASA
comes out with more and more evidence of life there and it has recently
changed from -- we found some fossils from long ago -- to -- oh shit --
looks like there was some snow melt in the past couple of months.
I don't think we are going to find any ETs but it's almost a certainity
that once humans arrive there, microbial life will be found -- not too
much to people like us but it's that sort of thing that will change the
world's perception about space exploration and will probably give it the
shot in the arm it needs.
I mean seriously -- when you have companies like DropBox and AirBnB
worth over a billion dollars why aren't we out there yet? It's not a
lack of money when one asteroid can produce more material than what has
been mined in all of human history to date.
It's a lack of promise.
