Are We Alone?

I think that there has to be at least some form of life in the universe. Since the universe is so large and there are so many places that could have conditions for life to form, I think there is probably life somewhere else in the universe. However, I think life could look very different than what we are used to. I think many other planets have different conditions than earth, so maybe the life on other planets breathes carbon dioxide gas instead of oxygen and maybe the most intelligent life forms have green skin. I think that there is probably life other than life on earth, but I think it looks very different and might be too far away for us to ever discover in our lifetime.
