God Almost Certainly Exists Zeno Strikes Back; the Revenge of the Eleatics!
(And your remix of the classic Witt line is perfectly apt!)
In all seriousness, you would think theists and apologists would learn from their history: tethering the truth of your religious/theological views to an unresolved factual/scientific question is a bad idea, because despite your faith and a priori assumption, you don't actually know what the answer to that scientific question will be. And so it is here. We don't know whether the universe is past-eternal or not: the science on the matter is decidedly NOT settled, and for all their admirable efforts theistic apologists (like Craig) have still yet to derive a logical contradiction from a past-infinite sequence of cases, or a past-eternal universe; the best they've been able to do is deduce counter-intuitive results, not genuine contradictions. But then, that's probably what one would expect even if infinite causal sequences are real- when your experience is exclusively of finite sequences, then infinite ones will inevitably run counter to your intuitions. So all they have on this crucial question is all they ever have: faith, and simply assuming or stipulating what they want to be true (and thus arguments whose conclusions are more or less indistinguishable from their founding assumption).
So as far as both logic and empirical scientific evidence is concerned, past-infinite causal sequences and cyclical and past-eternal universes remain very much on the table, even in light of the accelerating expansion of space/dark energy: you have eternal inflation, Penrose's conformal cyclical cosmology, the bouncing universe of loop quantum gravity/loop quantum cosmology, and so on. All viable models. You even have viable models that exclude a past-eternal universe, but remain unamenable to theistic interpretation, like Hawking/Hartle's "no boundary" proposal where the universe is in some sense past-finite but nevertheless lacking a beginning or start (and therefore lacking any causal role for a creator, at least in any horizontal or sequential sense). And this is all in addition the fact that our efforts to model the earliest stages of the universe are likely futile because gravity would be significant enough to dominate on the quantum scale, and so our lack of a quantum theory of gravity likely makes most of our efforts moot (indeed it would be sort of a miracle if we managed to stumble on a correct description of the early universe, despite lacking any viable theoretical framework for this period).
So despite Devans and others religious conviction on this matter, there is nothing even "almost" certain about any of this... other than the fact that their arguments are patently unsound and even somewhat arbitrary.
