@ughaibu,
I agree that you can't prove that God exists, however I am interested that you find the claim that you can so offensive.
I believe neither the existence nor non-existence of God can be proven, because God is a 'transcendent being', God is 'beyond existence' and not the kind of thing of which either existence or non-existence can be asserted.
So I will go back to what I said before, which is, you can't prove that God exists, but you can prove your faith in God by the life you live.
As far as the relation of faith and science, at other times in history, these have been understood to be two aspects of an harmonious whole. However many people in the modern world believe they are opposed to each other.
