Not really. How do you know for sure that it he is interested in the mundane actions of every individual person? Even if he is interested in man, that doesn’t automatically mean the Torah is from him. There are a lot of steps, each of which must be carefully argued out.

I am simply saying that proving the existence of God alone doesn’t go very far in proving that our version of Orthodox Judaism is what God was interested in when he created the world.
