I constantly hear the speculations over the possibility of intelligent life elsewhere in our universe from people who completely dismiss any possibility of a Creator God. I find this extraordinary to say the least. I know this thread will spark a contentious debate but I believe it's one well worth exploring. This, of course, is simply a matter of philosophy, which is why I chose the Religion and Ethics forum instead of Science and Technology. We have no evidence life exists anywhere but planet Earth. I would like to set aside the various arguments for religious philosophies and focus on the aspects of logic and reason in examining the question at hand. Does intelligent life exist elsewhere? The primary argument to conclude that it likely does, relies on the sheer number of stars and planets. Because there are trillions of stars and each one is likely to have a rocky planet in a zone compatible for conditions of life, some will assume the possibility is very likely. I would like to disabuse you of this notion. First of all, we have to consider that intelligent life on this planet is the result of many circumstances over the course of 4.5 billion years, if we are to believe the modern scientific theories regarding evolution, etc. We'll stick with the current scientific parameters as opposed to quirky young earth creationist dogma, and let's see how this works out. We don't know how life originated. Whatever happened was extremely unusual and rare because it doesn't seem to be happening anymore and there is no evidence of it happening anywhere else. But let's take for granted that some mysterious combinations in the forces of physics and nature combined at the perfect place and time to originate life on Earth. It seems reasonable to conclude the unique conditions of our planet may have contributed in some way, but they certainly contributed to the "evolution" of life once it had originated. Our wobbly orbit, caused by a careening body which formed our Moon, which fell into perfect geosynchronous orbit and caused tides and seasons to happen... all of which tremendously contribute to the sustainability of life and life cycles. The presence of abundant water in liquid form. A molten iron-nickel core which gives us a protective magnetic field. Atmospheric pressure which prevents our liquid source of water from evaporating into space. And dozens of other things which contribute to an environment conducive to life in general. Logically, when we begin to narrow down the billions of possible planetary candidates which could even support life, the odds become exponentially less and less with each of these criteria applied. Okay, so maybe one in a billion planets could support life? That still means there is a good possibility it might exist elsewhere. But what form does it take? All we have to go by is what data we have here on Earth. Nature, left to it's own evolution, produced a planet teaming with dinosaurs. Big giant lizards and flying reptiles... nothing approaching intelligent life. It took a rare cosmic event, supposedly an asteroid striking the planet and wiping out the dinosaurs but not wiping out all life forms. From there, the reemerging life spawned mammals which gave rise to primates and then humans. So now we have at least two distinct cosmic events of interaction, the moon collision and the asteroid that killed the dinosaurs, which had to happen at a precise point in time for there to be any form of intelligent life on Earth. And that is if you don't count whatever cosmic phenomenon gave us all the water while no other planets around us seemed to get any. Setting aside religion, at some point, don't you have to consider the number of miraculous events which had to happen as they did, for intelligent life to exist here? What would be the odds of those same events happening elsewhere? I believe it is all but impossible that another intelligent life form exists elsewhere unless there is a Creator. A force beyond the physical which intelligently set into motion the precise events and phenomenon which had to occur for intelligent life to emerge.
