See there's the difference though . If science says something is expanding the universe at an accelerating rate but we don't know what yet.... And a religious person counters that the thing accelerating the universe must be God. Then simply God because an answer to questions we can't 'CURRENTLY' answer. It becomes the God of the gaps an all powerful being we invoke in areas we currently can't explain which recedes once we do understand the process behind the acceleration and so on with the next mystery until that's answered and so on and so on infinatum. Basically God is a forever receding pocket of ignorance/lack of knowledge and becomes nothing more then an excuse until the answer is found.
