Scientists are having trouble counting all the planets in this galaxy alone. If life really will "find a way" then it's ubiquitous, I think.
Now, life that rises to our current level and survives on from there, that's far, far less likely. And if they did it could have been long before us, and so far away we'll never know them. This is perhaps lucky for us. (We do breed well in captivity.)
