You are called. You are challenged. Got it? This is where you show the hand or fold.
You have this backward in that ID posits that that irreducibly complex organisms cannot be the product of gradual development over a long period of time. All of the parts must be present from the beginning, not that it will stop working if parts are taken away. It is the origin of the parts and the controlling instructions that are in question.
Mutations over a long period of time would not account for all of the elements of the biochemical processes for blood clotting, for instance. If it takes 11 chemical reactions, in sequence, to produce blood clotting, what would account for the first chemical reaction?
And what would that process do while waiting for the second reaction?
What would the organism do while it was waiting for the reaction that would trigger the process?
More importantly, what would it do while it is waiting for the chemical reaction to turn off the process?
Where would the instructions for controlling this process reside?
ID is not about change, it is about origin.
ID is not just about the origin of the structure, it is also about the origin of the process control, as well.
Evolution says that all of that came about over a long period of time, by random chance, unguided and without purpose. It would also lead us to believe that somehow all of this randomness can account for a highly sophisticated, complex system coming into existence - natural selection assessing each mutation, keeping "useful" changes, rejecting each "un-useful" change. And yet, how does a random chance process define "useful" and "un-useful"? How does the organism "know" what is "useful" and what is not? It doesn't even "know" what the end product/process is going to be...how can it assess usefulness?
This all begs for some kind of controlling intelligence.
