I can only add that this subject relates directly to evolution/creation belief.
Either we're alone or we're not. If evolution is true, we're not alone. Looking at all the weird animals in Australia - and Madacasgar (cut off from the rest of the world), I see that evolution works. I used to hold that it has never been observed that a new, unique species has ever emerged that cannot reproduce with its parent species. This was true (as far as I know) but no longer so. Thus,....... I now understand why scientists think about life on other worlds where ever they see some warmth and chemicals.
I also was impressed by the rationale for the 'Gold' Theory - which holds that most of the weight/density of the planets could be bacteria !! The reason why is that lots of such were found in deep drilling of earth's crust - hence, warm planetary cores could be much the same. Mars might be alive deep underground, as well as the rest.
That said, I will admit to some doubt or great curiosity about 2 things in regard to aliens:
1) how do they survive amidst full abundance? How do they live without necessity? Or goals that have importance? What do they do for entertainment if they don't need to work? (think about what happens to people that win the lottery)
2) How did they avoid blowing themselves up as we humans threaten to do? Are they like bees or ants that way? Or psychic maybe, so they don't worry about stuff like Newtown happening?
