Yes, a nice huge number, but isnt saying much, appearing as murky as the rest of the equation. The parts we know, and what we dont know. And what we figured out so far tells us higher lifeforms are not as common as the myriads of stars and planets suggests.

Complex life evolving from simple cells is an inevitability given the right circumstances and enough time. With trillions of planets multiplied by billions of years it's quite likely that complex life forms exist, even in this very galaxy. Not that we'll ever find out since even the confines of our own galaxy are too big to grasp for a human. And there are billions of galaxies out there.
