In order to be a scientific theory it must make falsifiable predictions. Since the creationist don't make any falsifiable predictions, creationism doesn't qualify as a theory, but more closely matches the definition of a myth:
1. a traditional story, especially one concerning the early history of a people or explaining some natural or social phenomenon, and typically involving supernatural beings or events.
2. a widely held but false belief or idea.
You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
You cannot over estimate the unimportance of nearly everything. John Maxwell
