To me its obvious that when you have several functions working together such as in the vision system, and the end result is being able to see, it is an intentional purpose. I guess I can never prove that so what is the point.
(This is not meant to be a facetious question...) If I saw a man pointing a gun at woman; saw a flash from the gun muzzle; heard a loud bang and then saw the woman fall over clutching her chest - I would say it was obvious that he had shot her.
Evolution is full of nothing but double speak. It has no thought, no purpose. no intent, yet constructs all the sophisticated systems that make up life.
The ironic thing is that you will now equivocate (in a sense 'double speak') about what 'thought', 'purpose', 'intent', 'construct', 'sophisticated', 'system' and 'life' all mean - or rely on too broad a definition.

The best I have ever seen any of you offer is some insignificant little bacteria mutation that shows nothing of how a sophisticated system can construct without intelligence.
You cannot build one single thing without conscious intent.
Again, you knowingly use words that have multiple definitions.
Build: To develop or give form to according to a plan or process. "You cannot build one single thing without conscious intent." is a circular tautological statement of no real worth.
Build: To form by combining materials or parts; construct. "You cannot build one single thing without conscious intent." is an untrue statement.
In the real world we see it takes conscious intent to design and build systems.
Another circular, tautological statement of little worth based on the unevidenced assertion that life is designed.
You are not making profound statements. You are not providing evidence of anything.
You are saying the equivalent of "Round shapes are circular!", but that is not evidence that shapes are circular or round. Your arguments are circular. Learn what that means.
