Life in Space

I don't think there is life other planets because nobody lives in outer space. Yes astronots do go in to space but they don't live in space . Also another reason why I don't there is life in
space is there is no air and from what I know U.P.S doesn't diliver to mares. So I think its
obvius that their isn't life in space.http://en.wikipedia.org/wiki/List_of_UFO_sightings
