Only then can we talk about how one would go about searching for clues of design. It does not require a supernatural entity. But chance is pure abstraction. My point exactly, it can be defined, predictions can be made. Your point was that chance is something real with instrumental power, very different from pure abstraction, in which case, it doesn't have any influence on any event.
Chance is a non-entity.
Take for example, a coin toss. Arguing for chance as a cause is arguing against logic. Random variation or chance is a non-being. Now I am confused. All words are to some extent subjective.
