What if God wanted to create the best of all possible worlds but didn't know how. Undaunted he tried anyway, the way we would try, by trial and error, creating creatures and then setting them in motion, doing what they do, God watching and learning.
He could intervene but won’t, because, like any good scientist, he knows that tampering mid-experiment contaminates results. World after world, experiment after experiment, he’s been learning, and applying what he learns, crafting new worlds until he gets it right.
His worlds are getting better, so good that we are within a hair's breadth of the native wit to make this the best of all possible worlds. Between our preprogrammed capacity to evolve, and learn from our mistakes, he has really high hopes that we'd be the one, the best possible world given the necessary physical limits and trade-offs whereby for one creature to survive another must die. Not ideal, but then God is a realist. You got to have physics and with it physical limits.
He’s got opinions about what we could do better, but sharing them with us would contaminate us. He keeps them in his notebook for use in his next world’s design.
There's theism, the belief that God runs the show manually in real-time, everything you do watched and potentially controlled by God, and there's Deism, the belief that God set it all in motion but can't or won't intervene.
