Once life is established, there is no reason why it would not eventually evolve into intelligent life with indoor plumbing and refrigerators with ice dispensers.
Sure, some slime will rise and die out due to extinction event asteroids and whatnot, but if there are billions of planets where the conditions for life are present, sooner or later one of them is going to give rise to Klingons. But don't worry. We will detect their reruns of I Love Kortar long before they arrive here and start stealing our water. So we will have time to prepare.
There is also no reason to suppose all life out there is inferior to us, but our detection methods are inhibited by the speed of light. There could be intelligent clouds on the other side of the Universe who have been around for billions of years, but their signals are only halfway here.
Or...
They say amino acids are necessary for life to get started. Earth did not have amino acids, so it was supposed that comets brought them here. Comets don't have the conditions for life, but they carry amino acids. Then milllions of them crashed into a place that does have the conditions necessary for life (Earth), and presto! Betty Crocker would be proud.
But...how did comets get amino acids? We answered the question of how Earth got amino acids, but now the question has just been moved to how did comets get amino acids.
In short, having the conditions necessary for life does not mean life is going to just kickstart itself. The odds of life may be greater than the number of stars in the Universe.
So we could be alone.
