I don't recall any verses where the bible addresses whether or not there is life on other planets. Personally, I'm 'agnostic' when it comes to intelligent life on other planets. Maybe there is, maybe there isn't.
I don't think all these 'abduction' stories and UFO sightings are true, however.
Given the millions involved,
even 3% ends up being quite a lot of poor abused, deceived, beleagured folks.
