yeah i dont belive in aliens in outer space.If they were such a thing as aliens, they would be humans from the future or something, that have gone back in time to try and help us save the none existing human race.and if there were aliens in outer space it'll probaly be us in a mirror universe that is more tecnologicaly advanced than our universe, and has traveled to our universe for some reason.Cause i dont belive there is any other type of creature out there other than humans.
some people belive that there are a countless number of universes that varie by just one small or huge factor.so there might be creatures outhrere that are advanced creatures from our planet in a mirror universe.
