God is actually not an explanation at all, regardless of whether there is any.When one truely sees God as the creator, reason is turned ON.
God created the laws, by certain laws lightning happens. Thus, God created lightning. Lightning is a part of design.
Theres more evidence for God then the alternative explanations.
An explanation is supposed to have explanatory power. Proposing it should have some form of useful consequence. It should help in predicting phenomena, their circunstances, their properties.
You are of course free to propose a divine will behind existence, but that does not ultimately explain anything. It is just an aesthetical preference with no discernible or detectable consequence beyond your own psychological mindset.
