It would appear that you are still struggling with chickens and eggs ... ID immediately infers a Designer thus it cannot be a closed system if it is axiomatic that the Designer is greater than the designed 'thing'. Those who would assert ID but deny a designer are playing contradictory word games.
From the ancient Sumerians to the Egyptians, Eastern systems and modern LDS, all infer a god—a designer—from within the system. In every case, the designer turns out to be humanized matter/energy.
So no, I am not struggling with chickens and eggs but unpacking and explaining to those who are interested, the consequences of closed systems.
