Sometimes I think that, sure, the universe it's huge and it's very possible (in my mind, almost certain) that there are other planets with advanced life forms like we can find here on Earth. If we accept this then it's safe to assume that not all life in the universe evolved at the same time. Most of the time we implicitly assume (probably because of sci-fi) that there must be a more advanced species somewhere but what if we actually are the more advanced species? From what we know right now it's just as likely for us to be the more advanced as it is for, say, the habitants of Kepler-22b. And somehow that feels more disappointing than if we were completely alone in the universe.
