Exactly, “god did it” is the exact same answer as “i don’t know”. If you believe god did it that is fine, the next question would be “how did god do it?”.
It’s also the wrong answer.
Supposing the god of Christians to be as Christians say - supposing there to be an entity Who is such: He has no causal function in scientific questions. So:
“Why is that man lying on the floor ?”
“I shot him, so he fell down”
is an appropriate answer. So is a description of the physics of shooting a bullet into living human flesh: it would lack a humane dimension - but it would be a valid description of what went on.
An inappropriate answer would be:
“Satan made me shoot him”;
or
“God told me to shoot Him - don’t blame me, blame God”.
The reason that Satan & God can’t be named as causes, is that neither is
controllable - their causal functions, however genuinely actual, cannot be shown to be causal functions, because they are entities outside science. Because of this lack of control, there can be no verification of causal functions. Because of this, the possibility of other causes cannot be excluded: if Satan or God can be plausibly named as causes, the Flying Spaghetti Monster cannot be excluded; the FSM might be the cause of the shooting. Or the dragon in my garage, or the pink unicorn, or the god Baal. If one un-controllable possible cause is allowed - so must others be.
“But Christians believe God made the universe” Of course; but that is theology - it is not science. Christians have their beliefs about the origin of the universe - and so do others. If the God or devil of Christian belief can be given the status of causes in science - so can the beings of other religions. If the God of Christians can function as a cause for science to take note of - so can the elephants who support the world on their backs. That Christians believe in the one & not in the other, is neither here nor there: Hindus believe in those elephants, and they are as entitled to muddy the waters of science with religious dogma as Christians. The only way of privileging Christian beliefs as causes in science, is to say that no non-Christian is capable of being a true scientist: IOW, to bring in a religious test. And that is as reasonable as would be talk of Catholic gynaecology, Mennonite physics, Anglican aerodynamics or Baptist electricity.
To say God is the cause of the universe,
as though God were a cause of things in the way that a lighted match causes fire, or fire causes warmth, is bad theology as well as bad science. It answers no scientific questions, and can be appropriate to science only at the price of undermining the theism it is supposed to clarify. It makes God into an object in the world - as though God were pinioned in a display case to be commented on, described, analysed. But if God is one cause among others, differing only from all others only in being the first link in the chain of causation, whereas all other links in it depend from Him, He is no different in nature from them. This is the theology of many ancient polytheisms: the gods were not transcendent, & not reducible to the created order: they were part of that order, differing only in being greater, more majestic, mightier than men, & (usually) immortal. God is not causal as created things are - to say that something (precious little) of Him can be known from His works, does not mean that, and cannot. God’s Holiness is His “otherness”, His separation from all that is not Him; this separation is the “difference” between the Uncaused God, & the caused universe. Creatures cannot bridge it - but God can.
Which AFAICS is why God is of no “use” for science, nor can be; & those who believe in a Creator-God have no reason to be alarmed by this, but should accept it as the good theology it implies. If Christians want scientific answers, they must use the appropriate methods; which are scientific ones. And that means they are not methods that have a god of any kind as an element in them. Why is it so important to Christians that God should be discoverable by science anyway ?
