As you may know from recent news releases, astronomers are excited to find 7 new earth-size planets orbiting around a star 40 light years from us. Of course 40 light years puts them way beyond our reach. It would take a space ship constructed with our current space technology 800,000 earth years to reach it. The main motivation for space exploration has always been our curiosity about ourselves, our origin, nature and destiny. So, we search for extra-terrestrial life or at least planets that could support life. Some people of faith are a bit skeptical or anxious about that possibility. So, I want to calm your fears.
What would it mean if space explorers found proof of extra-terrestrial life? Many people of an atheist bent would conclude that discovery of life elsewhere would disprove divine creation and prove that life here happened by chance. I suppose the argument would have to run like this: since we have another example of the evolution of life in the universe, we know that life on earth is not so unique and improbable that it requires a miracle to explain it. Instead, life tends to arise wherever in the universe conditions are right. And those conditions are not limited to earth. Hence we must assume that life arose on this planet by chance when the conditions made it possible.
Is this the only, or even the best, way to draw out the implications of such a discovery? I think the opposite is true. As long as earth life is the only instance of life we know, we could plausibly think of it as a freak accident unrelated to any purpose. Physical law made it possible, but chance made it actual. In truth, if we found life elsewhere it would make less plausible the idea that life on earth was a chance event. If we discovered that the universe was teaming with life, it would completely destroy the idea that life on earth came about by sheer chance. Why? Because it would demonstrate (at minimum) that the universe has a built in tendency to produce life, ultimately intelligent life. The occurrence of life could never again be attributed to pure chance. We would know it to be matter of law! The law of life would be as much a part of the universe as the law of gravity or any of the other fundamental forces. At its origin, the universe would have been programmed to produce life, to produce us. Producing intelligence is the universe’s goal. And when you and I think and dream and pray, we are enjoying the activity the universe has been aiming at from its origin! Our experience of our own minds is the most powerful telescope or microscope conceivable. It is a window into the beginning and end of all things.
But how could intelligence be the law and goal of the universe unless Intelligence was also present at the origin of the universe? As long as we think of the initial laws of our universe as mere regularities in a material universe—a rather unimaginative viewpoint—we did not have to raise the question of divine creation. But when intelligence comes to be considered an inbuilt aim–as the discovery of instances of ETL would force us to conclude–this explanation will no longer work. Intelligence is not a mere regularity but a real thing indicating the presence of a mind. If the goal of producing intelligent beings is part of the initial conditions of the universe, the only explanation of this fact I can imagine is that a super intelligence programmed it that way.
Hence far from believers have something to fear from the discovery of extra-terrestrial life, we should rejoice at its discovery and say to our atheist friends, “See, we told you this universe was created by Life for life, by Intelligence for intelligence.” It is the atheist who should hope that we are alone.
