When I think about what life might be like beyond Earth, I try really hard to be objective. I think it might be bias to say alien life will look like bacteria, or if it’s more evolved, it’ll have eyes, legs or wings. Considering we only have a sample of one to go by (life on Earth - DNA), I think there’s a chance alien life may be unlike anything we have ever seen. It may be so different that it makes the diversity of life we have here on Earth look completely uniform. It may be so different or so much more intelligent than us, that we wouldn’t be able to recognize it. Of course I have no idea, really. There may be life similar to the kind we’re familiar with, and some very different. Let’s just say I’m reserving judgement until we actually find life, and keeping all possibilities open. As for Kepler 22b, it’s possible it could have life, especially since we know life can exist at its distance to its star. SETI has started to search the planets that the Kepler mission is finding (http://news.discovery.com/space/seti-to-hunt-for-aliens-on-keplers-worlds.html). I think this is the most exciting time for SETI yet. I’m sorry I didn’t really answer your question, but I don’t feel as though I’m in any position to have a clue or even opinion as to what might be out there.
