Let me see if I understand you correctly. What you're really saying is that; by doing empirical research using the scientific method, creationism CAN lay claim to an association with science. Did I get that right? I thought for a minute there we were in disagreement.
No I guess you're really saying it is impossible to use empirical research using scientific method to prove creation theory.
My friend, using the worst case scenario we are on equal footing because the same is true of the religion of evolution.
That's my story and I'm sticking to it.
