I argue that the following two claims provide us with sufficiently strong reason to conclude that God came into existence from nothing a finite time in the past: that God is omnitemporal; and that there is a first moment of time. After defending the possibility of God beginning to exist ex nihilo from various objections, I critique two alternative attempts at providing an account of the relationship between an omnitemporal God and the beginning of time. I show that these either (...) fail to be an alternative to my own model or are less supported by the relevant evidence. (shrink)
