however the numerous "hindsight" experiments including the evolution of moths in the UK throughout the industrial age to the present demonstrates an attempt of experimentaion.
and also:
Exactly what kind of experiment, hindsight or otherwise, can one conduct to prove intelligent design?
Both of these statements display a misunderstanding of what the word "experiment" means. You are talking about retrospective studies, which are fine as far as they go, but not experiments.
Of course I agree that if the second statement is modified to say:
Exactly what kind of study or experiment can one conduct to prove intelligent design?
The answer is "none".
And I certainly agree that "intelligent design" is "intelligently designed" to be unprovable. That's why I used the word "obscurantism" in one of my earlier posts.
