There are a lot of planets out there. God is the first cause and took an interest in us because we have evolved into beings that have moral awareness and are aware of God. God knew we would exist. He knows the future. It was his plan for us to exist. Predestination. But just because he knew we would exist does not mean that he actively directed evolution. We are in the figurative image of God. We feel, we create, we destroy, we love, etc. God's logic is not man's logic. He is an unfathomable spiritual mega super mega super mega super mega super mega super entity.
