Exactly. God created the physical laws that made life possible. To believe in a literal creation is akin to believing that everything that ever was, is, or will be was predetermined and free will is an illusion, since nothing, even on the atomic scale, would ever be able to happen without the direct intervention of God.
This whole idea, the basis of Deism, was controversial in Newton's day, and found a focus in the wording of Halley's Ode To Newton, which was published with the Principia. Halley's original verse had a line expressing just what you said, that God did not set aside physical law in His Creation. This was objected to as denying "Providence" - the ongoing intervention of God in worldly events. Some busybody minister got a hand in it and altered the lines in the second addition to remove the objection, but they have since been restored.
Or possibly it is God's existence that makes it possible for anything and everything to happen.
The quantum foam is the low hum (or OHM) of God. It is the source of energy for the entire physical universe. Without it, nothing exists.
God is many things to many people. Which seems very wise of God.
