Well, "Intelligent Design" is nonsense, but your illustration above is just another variation on the 'Problem of Evil' (i.e., how can God be all-powerful, all-knowing, all-good and yet permit evil to exist). The short answer is that if an all-powerful, all-knowing God exists then he isn't all-good by our standards.
I don't see it in terms of good and evil. If the word "intelligent" is paired with the word "design," then that conjures in my mind ideas of efficiency. It's that which I am trying to get to, not religious connotations.
If intelligent design is to be taught in schools as a an alternative scientific theory, I want to understand its underpinnings
