That is not true but I have heard it a lot. In fact many evolutionists claim to believe just that. They say the Bible says who did it (God), but it doesn't say how he did it (evolution). That is precisely "God did it and then looking further after accepting that God did it.
So it can be said quite logically that you are wrong in your statement that people cannot say God did it or they end science right there.
On the contrary, you can say God did it and then take it apart and look at it your whole life and see how it works and how He may have done it.
yes you are right
