Cop-out. Not unexpected.
No, I was demonstrating that if there is no evidence - the assertion cannot be refuted. This is why the Burden of Proof is upon the person who makes the statement, there must be some level of evidence to justify the assertion. (Unicorns exist, ID is science.)
Saying that natural process "cannot" have produced "irreducible complexity" Begs the Question that it cannot and asserts a premise for which there can be no evidence, Proving the Negative. You have to prove that a Negative can be Proved, not the other way around. The Burden of Proof is upon you.
I am not so naive as to think there is anything that I could write here that you would accept as "proof."
But then again, I don't have anything to prove.
