Well, it depends on what type of life I guess. The environment needed to produce life as we have on Earth is rarely found in the universe, to date we know of only a few planets outside of our solar system close to what is required. However, if the type of life is different from our own (which it very possibly could be) then the enviroment required could be completely different from what we need to survive.I'm undecided, due to the vastness of our universe you would think that there would have to be life somewhere, but we haven't found any evidence yet, so it's difficult to say.
