Zan, you are confusing me now.
I believe smoking is completely different to what I am talking about. Smoking is an actual addiction that causes physical harm. Are you implying this of religion? You believe God doesn't exist Zan, but many do. Who are you to say that they have been fooled? I believe this is slightly arrogant of you Zan.
A footballer will pray, thanking God for his blessings. This is his choice. I do not believe it comes from a 'need'. Consider this scenario: If A asks B, why do you need to believe in God? B answers, because he exists. A states, why do you feel the need to believe that he exists. B, because he does. See where this 'need' argument goes?
With regard to Stephen Hawking; of course, if you discount the possibility of God and look at it purely from a scientific point of view, then yes, there is no point in questioning any further. However, if you are open to the concept of spirituality, then you will question further. This is obvious. Especially when considering, that when science brought forward the theory of the beginning of the Big Bang, it meant a beginning, which fits in perfectly with religion.
