Suppose you observed a pattern in the stars that spelled out “Hello, this is God talking to you. I am the God of Christianity.” Many would find it ludicrous to suggest this happened through the blind assortment of stars operating through physical laws. Many, in turn, would suppose that it is, after all, the Christian God who did this.
But what about the probability of the Christian God existing Himself? Dawkins argues that there is nothing more complex than this Christian God given His capabilities and attributes and deems Him to be improbable. Clearly, the “probability”, or atleast “plausibility”, of this type of God matters. If He is impossible or extremely implausible, His existence may be even more implausible than those stars aligning in such a way to produce those words. If He is less implausible, then it seems rational to prefer this explanation over blind laws creating that star pattern.
Now, the traditional conception of the Christian God is that He is eternal. Suppose instead He began to exist. Does this reduce or increase His likelihood? Something about this kind of God coming about randomly seems to be even more implausible/improbable than Him just always existing.
Is this a mistake? If not, which idea of God is more plausible or probable?
