An extensive look at the actual writings and arguments of those in the ID research community reveals that intelligent design is not an appeal to the supernatural, nor is it trying to "prove" the existence of God. The consensus of ID proponents is intelligent design theory does not allow one to identify the designer as natural or supernatural, because to do so would go beyond the limits of scientific inquiry.
Here are some excerpts from ID literature making it clear that ID is not an appeal to God or the supernatural: "If science is based upon experience, then science tells us the message encoded in DNA must have originated from an intelligent cause.
But what kind of intelligent agent was it? On its own, science cannot answer this question; it must leave it to religion and philosophy. But that should not prevent science from acknowledging evidences for an intelligent cause origin wherever they may exist. This is no different, really, than if we discovered life did result from natural causes.
We still would not know, from science, if the natural cause was all that was involved, or if the ultimate explanation was beyond nature, and using the natural cause." (

Is Intelligent Design Theory Really an Argument for "God"?
