Put it this way, imagine trying to find 4 needles in a haystack as large as our solar system. We might get lucky and detect communication, but even then alot of that would depend on our species to focus resources to do that instead of spending it on weapons and war.
It is more likely than not, that life exists elsewhere, but again, because of distance it makes it extremely hard to figure out where life would likely survive in the universe. But we do know right now, water exists elsewhere which is the most important thing for life to exist.
But again, make the distinction between life at the bacterial level (which I agree is most likely quite common) and life at the technological level. At this point we have no chance of detecting non-technological life beyond our solar system.
But, if there was a technology at the level of manipulating stars, there is a decent chance we could detect it. There was even a false signal recently thinking there might be construction of a Dyson sphere around a nearby star.
Detecting those 4 needles becomes a lot easier if they are luminous. The question is, if there are truly advanced technologies out there, why are they dark to us? And if not, why not?
Again, even life at our level would be likely too. But again, the universe is so big, it is still that needle/haystack for them and us.
Distance. While there could even be more advance life then ours, because of distance, it would most likely be just as stuck locally where it is, like we are, even if it had a slightly longer range. I will say this though, if I were intelligent alien life, and spotted us, with the way we behave to each other now, I wouldn't try to contact us even if I could. We are a very violent species.
I really do think you are over complicating this. It only takes water and amino acids for evolution to occur. As individual atoms, those atoms are plentiful in the universe. But no, I still do not buy any Area 51 or Roswell crap.
In theory if we could go to every rocky planet in the universe, as big as it is, we should expect to find life at our intellectual level. But again, distance and time and energy are going to make it almost impossible for life to communicate with each other over those distances.
