Did you know that within 1000 lightyears of planet Earth are 30000 planets suiteably distanced from similarly typed stars, in other words, 30000 potentially Earthlike planets exist in our local galactic neighbourhood.
It stands to reason then that at least some of these planets are capable of supporting life, and if it was only 10% of those then that's still 3000 planets being life supporting, or even 1% which would be 300 planets. Hypothetically speaking of course.
We still have no evidence of life on other planets on account of the only planets we've visited with our probes are not suiteably distanced from a suiteable sun.
Indeed sending a probe to a potentially life supporting planet at this time is still a little impractical on account of the huge distances, even 1 light year is so far away that the probe would have to travel beyond the bounds of my ego.
Scientific advances are moving at a rate that it's better to wait 10 years and get there 50 years earlier ... and so on and so on, until eventually we've spent all of our planets resources and the scienece becomes moot, or we've evolved into post holocaust amoebas.
Of course if there is life on other planets. Actually let me rephrase that, there IS life on other planets but on the chance that it is intelligent life what are the odds of that life being anything other than petit warlike creatures held up by the dogma of it's local religions?
I seriously hope there isn't intelligent life out there in the universe, because the thought of the rampant criminal sociopaths (ie: clergy) on our own planet is depressing enough, but multiply that by the magnitude of the universe and what we've got is a universe full of repression, suffering, and injustice.
I for one would rather believe that the universe is a little better than that.
It's such a shame that i'm wrong.
