Auto junkyards are indeed the ejecta of man's well-known designs. Not a problem. As I said, we have evidence of man designing things. The concept of man-made design is understood, but does not of itself prove -- or even give evidence for -- the ID conjecture. All your claims and conjectures notwithstanding, we have zero evidence of some celestial designer tinkering around with DNA.
You seem to be both agreeing with the evidence yet disputing its validity (a decidedly self-contradictory position to hold).
You agree that Man is intelligent. You agree that Man has designed things (including programming DNA via gene-splicing), yet you dispute that there is any evidence that any intelligent process tinkered with DNA.
Also, what does your introduction of a "celestial" designer have to do with anything? If one intelligent process can be shown to design DNA, then other intelligent processes are not needed to validify the theory of Intelligent Design.
