It's a near certainty that life exists outside of earth because the universe is predictable and apparently deterministic (exactly why we can conduct scientific inquiry into it) as opposed to the creationists' conception of nature being unpredictably whimsical with gods controlling it at will.
The formation of life is relatively straightforward giving the right conditions and ingredients (both of which are more than abundant), that you can easily INFER the existence of alien life somewhere else in an unbelievably massive universe. There's no physical evidence yet. It's still pure statistical probability. Rationalism (logical deduction based on already known variables and conditions) and empiricism (observational evidence) are both properties of science. Aliens are logical that's why scientists are continually hunting for their evidence. God's are not.
The only way for life to be impossible to exist outside earth is if there's a god who has, apparently, only decided to create one planet with life in it.
There's no "other side of the fence" in science and philosophy. Both disciplines, as aforementioned, are characteristically materialistic and atheistic. There's no theistic science, and theism is confined only in an insular, stagnant philosophical subdiscipline. Theist scientists/philosophers are a fringe minority who have to compartmentalize their irrational magical beliefs and their profession with a great degree of cognitive dissonance.
First, you grossly misunderstood. Typical of you. When I say other side of the fence, you have to dig deeper, explore further, digest even it's hard, the other arguments that are equally intellectual as the opposing side(atheism and/or theism). Of course it is purely biased when we based all the atheistic claims on your arguments. I tell you, your arguments here are old as stale and no longer effective. There are hardcore atheistic arguments that deserve further, deeper, rigid, analytic, logical reading and consideration. Do you think, mainstream or theist philosophers only thinks of the arguments where you syperficially treat their arguments?
Second.. Where is the evidence that life else where in the universe exists? Okay, I dont argue there is no other life beyond earth....but....whetr is your evidence?is a hypothesis no matter how intelligently constructed be called an evidence?? Besides, we can not argue that maybe in the future life elsewhere would be discovered..this is a mistake if we debate where scientific findings are involved. As long as somethings arent proven that they exist, we cant use them to validate our arguments. Furthermore, existence of life elsewhere in the universe doesn't invalidate the existence of a God/Gods or the theistic claim..if we hypothesize, life elsewhere, why don't just we hypothesize an infinite dimension where there might be of higher beings???
