What do you think of this representation of theism?

Consider one of these two pictures of a gravitational well:

Now imagine that the net in which the ball is, is infinitely big. So just imagine that the net doesn’t have the four edges, but goes on forever.
Now imagine that the net represents nature (everything that is known to exist), and that the ball represents God.
I want this imagined model to illustrate that God is the hypothetical being that is the basis of everything that exists.
Please tell me what you think of this representation of theism, not what you think about theism!
