If God wrote a novel, would they have to query to get a literary agent?

I wouldn't know.

Can you write a novel?
If so, would they have to query to get a literary agent?

Why would He be interested in writing a novel?
Why do you use they for one God ?
Why would he need a literary agent? One can - even without being a God - get books printed on your own costs.

I ask because if writing a novel can be the outcome of billions of years of history and evolution, it seems fair to project that idea onto God.

God wrote every novel ever written.
And read thus, too.
