If option one is true, then there should have been some evidence of a positive nature to indicate that, and that something shouldn't be limited to the imaginative folklore of superstitious primitives. Also if option one is true, then nothing in the universe makes any sense anymore. If option two is true, and that seems infinitely more probable, then there is order in the world, and science has value where it couldn't under option one. But there are few (if any) absolutes under either option.
I suddenly feel like we are hijacking this thread, but let's deal with it for a moment and if we need to move the discussion I'm good with that.
1. If God does exist
a.many believe that there is positive evidence for God, things like the beauty of life, the complexity, history, spiritual renewal. I even resently read about an experiment done in which a person was weighed before death and then again at the moment of death in order to see how much the soul weighs. Interestingly, there was a weight difference. This would indicate some kind of positive evidence of the supernatural existance of a god. We could go on, but we don't have all day. The very world around us, boasts of a force or being beyond the chance and it is this very evidence that seems to be at the core of the creationists belief. (now before you judge me as a creationist, I do not hold to the traditional creationist beliefs so don't even go there or this will turn into the usual abusive debate real soon. You need to listen to what I am saying not label me)
b. The universe suddenly does make sense rather than not make sense. If God exists then there are forces outside our world that control our world. For example, why does the wind blow, where does it start? The wind has no beginning or end. What makes DNA function, how does the mind work, we know some basics, but for every qestion we answer there are infanitely more to ask, this makes sense if there is a God who created it because it means that a being greater than our intellect created. In fact, the bible tells us that it is good to explore and look for the answers that God has hidden from man. That in short means that God wants us to be scientists, asking questions and exploreing.
2. There is no God.
a. As to probability, that would be very improbable but that is another discussion all together and your premis seems to be that there is no God so we will leave that one for the moment.
b. It does nothing more for the need or desire of science than if there is a God. In fact, see above where the bible encourages exploration and questions.
So then what are we left with. From a scientific standpoint, either option is possible. From a logical standpoint, there is more evidence to support God than not. So you need to sit down with your scientific mind and ask yourself if you are as scientificly minded as you think you are. You read the words I type, but you can not see me nor evidence my existance beyond, do you believe I exist? God put His fingerprint all over the place, but if your premis is that He doesn't exist, He won't exist for you. Plain and simple, just doen't go around saying there is no evidence, there is more evidence for His existance than for His non existance.
