As far as I can tell, the Bible is silent on the question of life that lives somewhere other than earth, with one exception -- angels. Several passages in the Bible refer to the stars of heaven and the angels interchangeably, and other passages discuss angels in heaven or cast out of heaven to the earth. [Genesis 28:12][1], [Judges 5:20][2], [Job 38:7][3], [Psalm 8:4-5][4], [Psalm 147:4][5], [Matthew 18:10][6], [Matthew 22:30][7], [Matthew 24:29-30][8], [Mark 13:25-26][9], [Revelation 1:20][10], [Revelation 12:4][11] > **[Revelation 12:9](http://www.biblegateway.com/passage/?search=Revelation%2012:9&version=KJV)** (KJV) > <sup>9 </sup> And the great dragon was cast out, that old serpent, called the Devil, and **Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him**. My understanding is that such passages have led to a popular belief that every star (especially the "morning star" and similar stars later redefined as "planets") has an associated angel, much like Matthew 18:10 leads to the popular belief that every child has a guardian angel. (This idea -- that each planet has at least one angel associated with it -- and other ideas that [Mason Wheeler mentions][12] -- is a big part of C. S. Lewis's fictional trilogy beginning with "[Out of the Silent Planet][13]").
