Assume for a moment that life is discovered somewhere else in the universe. How does extraterrestrial life fit into a Biblical framework? If alien life is found, would it completely undermine the reliability of the Bible? A proper answer to that question would depend in part on the kind of life discovered. Before beginning to answer the question it is important to remember this is all hypothetical. No life of any kind, no matter how tiny, has ever been found anywhere else in our solar system. Some claims of evidences of life or the existence of materials necessary for life have been made, but those claims are notoriously difficult to test and verify. At this point no evidence exists that could reasonably lead one ot conclude there is life out there.
Popular science fiction focuses on alien life that intelligent or semi-intelligent. Of course, a movie about alien bacteria floating around in alien pond scum growing, dividing and floating around some more is about as entertaining as an elementary school biology film about the habits of earth bacteria. Science fiction entertainment requires alien life that is intelligent enough to produce conflict and drama. Intelligent life is not the only kind of life on earth. Consequently, to answer questions about alien life and the Bible one must consider the many different kinds of life.
From a Biblical perspective, alien life is not necessary. The purpose of God in creation is the revelation of His own glory. Life on other planets or in distant galaxies is not strictly necessary for the accomplishment of God’s eternal purpose. Of course, one could argue that life in the bottom of caves, under the Arctic ice and in the darkest depths of the ocean is not strictly necessary for the revelation of God’s glory. Regardless, from a Biblical perspective alien life is not neccessary to understand what God has revealed or for the accomplishment of what God has promised.
If life were to be discovered in the universe, it seems to me that microbial life is the most probable. The tiny bacteria that breakdown and recycle the elements of this earth might be found somewhere else fulfilling the same basic role they fulfill on the earth. Such a discovery would offer no proof of evolution, would not contradict any teachings of the Bible nor would it undermine any Biblical principles. The discovery of microbial life outside of earth would have no real impact on the Bible, creation or a Biblical worldview.
The discovery of a slightly higher order of life, like plants and animals, does not seem to be that likely, but granting the possibility for the sake of discussion what impact would such a discovery have on the Bible and Christians? Imagine in some future generation scientists develop a space ship capable of making the journey between the stars. During one an exploratory trip astronauts find a jungle planet, teeming with animal life. What impact would such a discovery have on Bible believers? As with microbial life, the presence of lower orders of alien life does nothing to undermine or destroy the teachings of the Bible. Life on another planet offers no more conclusive proof for evolution than does life on this planet. All such a discovery would mean is that God created other planets teeming with life that show off His power, majesty and eternal Deity.
Unfortunately, space has run out for this answer, so we’ll have to take up the matter one more time in the next article and consider a Biblical theology of intelligent alien life.
