I am an astrophysics student. IF life of intelligence was ever discovered elsewhere in the Universe, what do you think their opinion on God would be, and how would it affect your opinion on God and the Bible?
If life exists elsewhere in this universe, then it would have been created by God since God created the entire universe (Genesis 1:1). If it did exist, God is the same being, so their knowledge of God would be similar to what we know of God from the Bible. So far we have found no evidence of such life and given the distances involved it is doubtful that we ever will.
Life existing elsewhere doesn't change anything for mankind. The purpose of our creation still remains the same, as well as our accountability (Ecclesiastes 12:13-14).
One argument for life elsewhere is that this universe is awfully big just to use it for mankind. But those who tend to think there isn't life elsewhere point out that eventually our world will be destroyed. "But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up. Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness, looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?" (II Peter 3:10-12). The argument is why should other intelligent life be destroyed because of mankind's sins?
Yet, even this argument isn't solid. II Peter 3 says the earth and the heavens (the atmosphere and outer space) will be destroyed. If this section of the Milky Way was destroyed, say by a supernova, which matches Peter's description well, there is nothing in Peter that necessarily requires the entire Universe to be destroyed.
So either way, I don't see the question being answered one way or the other from the Bible, nor do I see it changing our outlook about religion.
