I actually thought you were joking...
If you believe that a higher power (i.e. god, allah, etc.) created the universe, but don't believe in a specific organized religion, that makes you a creationist which is still a religious belief!
We may be talking semantics here but saying god and religion aren't the same thing is like saying a car and an engine aren't the same thing. You're right but it's an integral part of the larger item, and generally useless without it's framework
