But I would argue quantum physics has presented us with definite evidence of an ID mechanism, namely the direct connection and involvement with consciousness, intelligence, and all matter. There is hard evidence for this, as anyone can verify by just reading the interpretations of wave/particality duality, and eminent physicists involved with such work.
I'm curious to what part of quantum mechanics you are referring to that is the definite evidence for an ID mechanism. I have a background in physics and I'm having trouble understanding what you are talking about. Please clarify.
