This article seeks to advance a Thomistic metaphysics of creation in light of certain claims made by Stephen Hawking on the beginninglessness of the universe. I start with an exploration of Hawking's proposal that a beginningless universe entails an uncreated universe. This propels me into Aquinas's contention that a created beginningless universe is indeed possible, and thence I consider the metaphysics behind Thomas's position in this regard. Given this metaphysics of creation, I contend that there follow some interesting conclusions with (...) regard to our notion of a creator God and the means for establishing the existence of such.
