If everything is designed, then we can't know it?If everything is designed, how can you say that you know what characteristics are exclusive to designed things? You can't. Irreducible complexity would be something that is a characteristic of designed systems and quite possibly un-designed systems. Until you started finding multiple un-designed systems without irreducible complexity you couldn't inductively reason that IC only occurs as a result of ID.ID focuses on biology. It doesn't require supernatural intelligence.I think it does require supernatural intelligence. If natural intelligence (which consists of many non-intelligent constitutents blindly following natural laws) counts as intelligent design then any ID explanation would also be a non-ID explanation. The ID explanation would just be much less detailed than the non-ID explanation (which would consist of many fundamental particles mindlessly following natural laws.)It is not equal to Christian theism.True, but its most enthusiastic supporters hold to both ID and Christian theism - and contradict themselves in doing so.
