That is a nonsensical and meaningless statement, since God doesn’t provide any information whatsoever on the sciences.
Suppose there was an alien in Andromeda who died a million years ago and thought about photons more fully and clearly than anyone in the history of the universe but never wrote a single thing or said anything about this to anyone. Would it be correct to say that he is the ultimate authority on photons? How does that even make any sense? Surely being an authority is more than simply the possession of knowledge about a thing. You have to communicate that knowledge also.
I certainly cannot find a dictionary definition which says that someone is an authority on something simply because they have knowledge about it. The closest definition I can find is being a source of information on something. And the simple fact of the matter is that God is not a source for information on science, unless you you are talking about the data we find in the Earth and sky and consider them being sent by God – I suppose that God could be considered the ultimate authority on the sciences in that sense.

People don’t write books – pens, printers, and typewriters do.
The comparison of the two creation accounts is well done. Thank you.
