I find this a very good subject to study, seeing that we will never know the infinite capabilities of the Universe and what it contains.I for one, completely disagree with anybody that says that there is no more life in the Universe. I find it hard to understand that somebody could think that we are the ONLY living planet in the ENTIRE supposedly infinite Universe (which is also supposedly always expanding).Although we may never see other signs of life, I believe they are somewhere out there doing what they do. They are unaware of us, we are unaware of them. Possibly they are well aware of us and are just studying us from afar. Either way, there HAS to be life.
