A theory is a helluva lot more believable then a bunch of here-say from people who believe in a supernatural being because they need to feel love, and an inner strength.
According to this theory, the world is approxomately four-point-five billion years of age. What's your point?
Since by God's very nature, God is omnipotent, he could have created the world yesterday, and you wouldn't be able to know the difference. The reason we can't prove God's existence is that our efforts are those of three or four dimensional beings trying to perceive beyond the fifth. Here's an illustration. Let's say you have created a world of two dimensional people called "Flatties", on a sheet of paper. The Flatties can percieve direction sideways, but there is no up or down for them. They can't perceive the third dimension. They can sometimes hear you speak, but there is no concrete way for them to prove you exist, since they can't look up out of their paper and see you. That doesn't mean that you aren't there though. You can see them, you can affect them, you can speak to them. But no one will ever see you, unless you touch the paper. Even then, they will only be able to perceive one single plane of your entire being. The same holds true to God, only on a more complicated scale. We exist in three dimensions, four if you count time as the fourth dimension. God exists so far beyond our perception that we could not prove he was there, even if we worked a thousand years trying. The only reason we can believe in him is because sometimes he speaks to us. The truth of faith is bound up in its name. It's belief without proof. It's a higher calling to a purpose that not everyone else can see, but that still exists.
If you have been bound, blindfolded and gagged and are lying on the railroad tracks, denying that a train will eventually come because you can't see it won't make a difference. And if someone who has the power to save you is there, and you can't see them, wouldn't you rather take a leap of faith, and in total helplessness, ask for their help? Or would you rather take your chances with the train?
