But my point was that we really can't claim knowledge of whether or not life exists on other planets, either from a religious or a scientific perspective. I think you've just confirmed that point, at least from the religious perspective. God has given us no reason to believe that there are other planets with life. On the other hand, He has not specifically told us that these other life-bearing planets don't exist.
I don't think that other planets in the solar system is mentioned in the Bible either.
