If I was to observe on half of a scale a feather laying elevated on the plate, then I could reasonably infer from my prior experience, even without seeing the whole scale, that some heavier force must be weighing down the other side, uplifting the feather. The creationist, however, would have no problem inferring extra qualities from the force; as it were, in this analogy, the creationist imagines a hand pushing the other end down.
From an effect we can infer a cause sufficient to produce it, but we have no reason to assign additional qualities, beyond that which necessity dictates. Why then, assume that the hand and not a rock produces the effect of the feather’s elevation? If you give the creating force any properties besides that needed to create (like omnipotence or lovingness), from what logic do they originate?
