Yes, science is science alright- and history has taught us that science is ever changing. What is thought to be valid today is often altered if not overturned tomorrow. Nature on the other hand remains true while science struglles to understand it. Granted, adherence to strict religious doctrine can result in limited thinking, but acceptance of a creation does not in and of itself imply limited thinking. It could open one's mind up much farther than those who place themselves in a scientific box because scientific evidence is always limited at any given time to the scant knowledge it has accepted as doctrine, and oftentimes even that evidence is later proven to be invalid.
If the big bang was the event that created the natural universe, how did it happen? Something had to be there beforehand to cause the force that created the natural universe, however that creation happened. What was it?
