Adonis, trust me, I am more intelligent than you and yet I believe in God. Why? Well, it would take a moron to truly believe that chaos and chance resulted in the incredible complexities of the universe. If you have ANY understanding of science it is just absurb to believe that there isn't some underlying driver that started things and allowed them to evolve as they did.
I don't like call anybody a moron in regard to metaphysics and not necessarily try to prove whether or not one is right or wrong because in these issues nothing can objectively be proven. How can I prove beyond a shadow of a doubt the existence of God? What I hope for is clarity. Just to be clear on the alternatives and the implications?
Either God has always existed and is the creator of all things or Matter, i.e, stuff, has always existed, never created, but just somehow just is, and due to the random concussions of arbitrary events we have what we have now.
Now, I'm sure TA's close reading, intellectual that he is, of Dostoesky's, "The Brother's Karamazov" will remember the telling line, "Without God all is permitted." Meaning that if there is no final arbiter of justice, no cosmic right and wrong, that a Mother Teresa and an Adolph Hitler share the same fate. That goodness, doing the right thing, morality -- really has no ultimate meaning. That one merely operates in accordance with their own personal self-interest with little or any regard on how it make effect others insofar as how those others may effect you (be nice to your boss so he'll be nice to you). There's no value system above and beyond what you feel personally is right and can personally justify and how much of your own selfishness or even ruthlessness you can stomach. In other words, there's nobody, other than yourself, you have to ultimately answer to. No eternal reward or punishment for the good or bad you have done in the world. Life, in the grand eternal sense has no real transcendent meaning. No reward for being good. No punishment for being bad.
This is, of course, no proof either pro or con but a clarification of a secular world versus govern by divine law. So take your pick: God and eternal justice or Matter/Stuff where transcendent morality is meaningless. I can't prove either but I do believe one's world view has a profound effect on how one lives their life. We use to have a saying in Philosophy: "Your metaphysics determine your ethics."
