God exists, because how could stuff come around that is so complex, and so highly unique, come about purely by chance.
Aah, you're referring to the argument from irreducible complexity. Creationists like to appeal to complexity, but introducing a Creator (
especially an infinitely intelligent one) just makes the new system more complex than a universe without a God, failing "Occam's Razor" (the most scientific solution out of all choices is the simplest one). Additionally, we must then explain the origin of the much greater comlexity of God, merely relegating the question of "creation" to an earlier time. Note also that evolution does not proceed by chance, a common misconception, and a "Straw man" argument. See the TalkOrigins FAQ on evolution and chance for a brilliant explanation.
also, by proving he exists, he would negate the faith part of religion, and believing he exists without proof is part of faith
Your argument is sound, but your premise is not (laws of logic here). This depends on establishing the importance of faith by its own merits, which you have not done, so you need to explain the importance of faith and, before even that, properly define it for me so that you do not mean
credulity (so much depends on definitions). If God revealed himself, it's likely 95% of people would join up to the new religion, and most
religious conflict would cease immediately. I simply to mot see how "believing without proof" is a virtue. Read in my signature a quote by Thomas Jefferson about how God would, if he existed, reward thinking ability not blind acceptance. This is reasonable, is it not?
because proof makes fact
Actually, proof does
not make fact. In science (in fact, in anything) you cannot ever positively
prove anything, you can only disprove (Popper's falsification). If something cannot be falsified, it is not science, hence the current string theory debate because it might not be testable. On the other hand,
facts are just observations, the raw data, and are meaningless without explanation. Facts occupy the lowest rung of the ladder of science, followed by laws, and then theories, right at the top. Hence the division of evolution into its "facts" and "theories" (see my earlier post in this thread).
and without faith god is nothing
Most certainly I agree with you. This also applies to Bertrand Russel's teapot orbiting Mars, and the flying spaghetti monster. They all require faith to exist. I cannot prove they exist, but I cannot either disprove they exist!! Creationists like to claim that because I cannot disprove God, it's like 50:50. In reality God is highly improbable, just like the microscopic celestial teapot.
so if he proves he exists, he makes it fact, and fact defeats faith
Well, my refined definition of "facts" notwithstanding, I agree!! May the day come soon.
and therefore god would make himself not exist.
You make it sound like his very existence depends on "faith" (by your definition). If no one had faith in Dr. Lazarus, would he cease to exist? (I hope not

). Nope, I'd still be here at my PC, and above all I'd feel happier if people genuinely knew of my existence rather than just had "faith" in me.
