For clarification, this is what I said:
"In order to formulate [a scientific framework / model for creationism], said framework would need to be testable, and that involves identifying constraints with which to test ideas. This is one of the biggest flaws in creationism is that because it relies on unbounded supernaturalism, there are no constraints to allow testing and determination of correct or incorrect hypotheses. Hence, why there are so many variations and contradictory versions of creationism in existence.
To be perfectly honest, I think this is an insurmountable hurdle for creationists."
I'm just not sure how one can test competing ideas that rely on supernaturalism. I've asked creationists repeatedly over the years on how to devise a method to objectively test such ideas, and nobody has come forth with anything.
As a problem that creationists need to solve, if it were solvable they would have probably already have come up with a solution.
