From biologos.org. So much more succinct than my ramblings..
“Many arguments claiming to prove the existence of God have been proposed throughout the centuries. The response to many of these arguments, however, is: “If God created the world, what created God?” It suggests that certain arguments for God’s existence only push the question of beginnings one step farther back. The Bible and Christian doctrine address this question by defining God as eternal and uncreated, but such answers rarely satisfy nonbelievers. A philosophical response is that God is the ultimate first cause; the atheist is left with a dilemma of what or who that first cause might have been. In the end, an uncaused creator may simply be a more plausible explanation for the universe we live in. Our universe appears to have had a beginning, to be finely tuned for life, and to have a place for love and purpose. These appearances affirm as plausible a prior belief in God.”
