Natural selection

Richard dawkins has a good point about natural selection. No doubt there is some truth in it or at least a modified form of the theory. i must learn more about this as its not something i really understood the first time round. even if it were true does this rule out a creator? i dont think science knows jack shit about what actually happened at big bang. they even admit this themselves sometimes. If evolution and natural selection are correct it still does not explain why this process came into existence.
