In fact, there is no reason in principle why every observable phenomenon could not be intentionally caused by the same invisible inhuman intellligence you speculate causes the diversity of life on earth.

If Cob is trying to explain a failing in ID reasoning by saying: 'if an inhuman, invisible intelligence (aka: God — or something like it) can be invoked to explain ID than why not suggest that it is the force behind literally everything else in the universe,' then he has just committed a false dilemma which is characteristic of people who actually don't understand ID hardly at all (which is kinda funny since he visits at least the ARN message board all the time — so you'd think he'd know better). In any case it is the same fallicious arguement that Pennock tried to throw at Johnson (,Phillip E.) when he essentially argued that if you permitted the supernatural into the courtroom (Johnson's arena), that the defence can claim literally anything.
Well, suprise-suprise, Pennock missed the boat. ID isn't about invoking the supernatural (even from the Christian-ID perspective), its about invoking design, PERIOD, nothing more nothing less. One can say what the want about the unscientific-ness of the supernatural, but design is a whole 'nother thing because unlike the supernatural, design is something that everyone deals with everyday, and thus it is indeed objective and empirical.

The problem with your argument is that you pretend that it only applies to mainstream evolutionary theory.

'Mainstream evolutionary theory' was the subject at hand. I don't think he was pretending; but he was being intentionally specific. It becomes increasingly difficult to write an essay about everything.

Yes in principal every observable event could be intentional. So? I don't follow your point.
