i think there HAS to be aliens and life on other planets. maybe not in our galaxy, but others, maybe. i mean, are humans that self-centered that they think they are the ONLY living things in the universe. I mean there are hundreds of thousands of other galaxies and planets, and i would not be surprised if there were another planet exactly like earth somewhere. as for the religious ppl who say the bible doesn't "mention" it- who's to say God HAD TO MENTION IT for it to be true. He doesn't have to ask us if it's ok if he makes another planet with people on it, right? who's to say we were just one experiment in many of His attempts at creating life? i mean, THERE HAS GOTTA BE MORE THAN JUST US!! don't u think? all opinions are welcome!!
