SCIENCE VS. PHILOSOPHY: I wanted to point out, in agreement with Donald Sensing, that science and philosophy are very different beasts. Science tells us the facts of the universe; philosophy helps us interpret them. There is certainly an interplay between the two -- philosophy may help determine what science investigates, and science may support or refute philosophy with factual revelations -- but in many ways they do not overlap.
Every scientist brings to their work a particular philosophy, similar to the "anthropic principle" that SDB mentioned. Our science is inevitably tainted by our philosophy. A scientist who believes that the sun revolves around the earth will perform experiments based on that belief, and it can take quite a bit of time for science to demonstrate that even a clearly observable belief such as that is wrong. Likewise, belief or disbelief in God naturally brings strong predispositions to the scientific process.
Science produces a lot of facts, and different people see these same facts and interpret them in very different ways because of their differing philosophies. While it would probably be possible to convince someone who believes that the sun revolves around the earth that he is wrong, the factual evidence is not so clear when it comes to the existence of God. In fact, as SDB has argued it may be impossible because God's existence cannot be proven or disproven. The question is, literally, beyond the reach of science. Where SDB sees the universe and concludes that it somehow spontaneously arose due to random processes, I see the same universe and conclude that it's most likely that it was created in some way by God.
How can we see the same things and reach different answers? Not because either of us is ignorant of scientific fact, but because our philosophies are different and we see only pale shadows of reality.
