Big Bang VI, ID vs. BB?

One poster theorized that intelligent design is as complex a theory as the big bang. I agree and submit that intelligent design may be even more complex because after science has gone down the rabbit trail of the big bang they are immersed in the reality of intelligent design. This is a kind of situation of not being able to see the forest for the trees. Should not science be as open to the theory of intelligent design as to any other theory to be intellectually honest? From human reason, can any philosophy within reason, stop short of explanation at the theory of the big bang and not go beyond theorizing that the complexities of the natural world defy theorems that offer only random chance and creation of everything from the building block of nothingness. Is mankind to be so shallow or is this as far as human reason can progress, only within our own intellect and not beyond to an infinite intelligence that theists call God.
