Wasn't that picture taken by the Hubble just a little part of the universe? You can easily tell that there are hundreds and maybe even more of galaxies just in that picture alone, which really helps show how huge the Universe really is. I personally think that there are other intelligent life forms somewhere, not in out Galaxy of course, but in other Galaxies, there is no way that we are the only intelligent life form out there. It's kind of a lame concept to think about though because since the Universe is so huge there isn't really a chance to find another intelligent life form in our lifetime, but I definitely think that there is a similar Galaxy to ours somewhere out there with life, there has to be. I didn't say much but I hope I kind of got my point across. Earlier this year in college, I was in the dorms with a few friends and we were just sitting around dipping talking about this exact concept. It's such an amazing and awesome idea to think about because it's so debatable, yet so unprovable at this point in time.
