Mormon scriptures are in accord. We believe that there are unumerable inhabited planets created by God. In Moses 1:33-39: God tells Moses:
35 But only an account of this earth, and the inhabitants thereof, give I unto you. For behold, there are many worlds that have passed away by the word of my power. And there are many that now stand, and innumerable are they unto man; but all things are numbered unto me, for they are mine and I aknow them.
For me these are some of the most intriguing and powerful descriptions of God. They are at the heart of Mormon ideas of the purpose of life and the relationship between man, God and creation.
When you consider that there are over 100 billion galaxies and tens of billions of earth-like planets in each of those galaxies you are really talking about an unimaginably large number of worlds like ours.
Later in the Pearl of Great price, Abraham sees a vision of the greatest of these worlds: Abraham 3:2-3
2 And I saw the astars, that they were very great, and that one of them was nearest unto the throne of God; and there were many great ones which were near unto it;
Evangelicals and others are quick to laugh at references to a planet Kolob. In a recent blog conversation I had with a few Evangelicals and I was told that the Mormon belief in the planet Kolob was simply unbelievable.
I really have no idea what Evangelicals think about extra-terrestrial life aside from these sorts of comments, but given the scientific evidence of other worlds, the evidence for extra-terrestrial life is far stronger than the evidence for a worldwide flood or any number of biblical accounts.
I do think, however, that christian thought is generally earth-centric. If no one is saved without knowing about Jesus while alive, it looks like the infinitely vast majority of God’s creation is just out of luck, or out of touch. If traditional Christianity hasn’t been able to effectively penetrate the Indian subcontinent, how can we expect it to penetrate the depths of the Milky-way?
Mormon thought seems to take into account of the cosmological reality a bit better than what I know of Evangelical thought. Am I wrong?
P.S. here is in an interesting related discussion from Parchment and Pen, an evangelical theology blog.
