The hocus-pocus isn't limited to just religious sources. We homo sapiens have been developing creation myths, with some sort of built in grand design, since the first one of us asked "why"? And as far as I can tell, every creation story reaches a point at which the explanation walks on wobbly legs at best, and is pure bull pucky at its worst. Despite knowing this, humankind continues to do it in an effort to bring "understanding" to something that is for all intents and purposes not understandable by our puny intellects.

I suspect that, through dumb luck if for no other reason, we have got bits and pieces of "creation" correct. As to the "intelligent design" part, it's any bodies guess as to the truth of the matter. But I would have to say that not having the capacity to understand something does not necessarily negate its existance. Therefore, some sort of intelligent design may exist, and it is a worthwhile intellectual exercise to explore the possibilities.
