Eternity, and not by Calvin Klein

Question from Brenton:
Is the universe eternal?

Answer by SmartLX:
We don’t know, but whether it is or not, neither option makes a god very likely.

Cosmologists now almost universally accept the Big Bang as a factual event which occurred about fourteen billion years ago. A far greater point of contention is whether the matter and energy in the universe have always existed, and were simply in some other state before they coalesced into the singularity which “exploded”, or if the Big Bang was truly the beginning of time and causality.

If the universe is eternal, there is no need for a creator god. Most theistic gods are regarded by their believers as eternal and thus in no need of their own creators; this is a real possibility for the universe itself.

If the universe is not eternal, and nothing material preceded it, then either it was created or produced by something or it emerged directly from nothing. Neither of these can be judged as more or less likely than the other based on our experience so far because, while we have no direct evidence of anything emerging from nothing (though quantum mechanics may suggest this possibility), we have no evidence at all of anything being created from nothing as creator gods are meant to have done.

That leaves the idea that something material (or with direct material influence) and outside the universe pre-dated it, and somehow resulted in its emergence. Again a god is possible here, but it could also be another previous universe, or the “quantum foam”, or any number of hypothetical entities. A god as an explanation is the least useful entity in this scenario because a full-blown intelligent god is itself an inexplicable cause, and it’s no more likely than any of the others. It’s also the only one which requires that we posit anything supernatural.

I realise that I’ve read quite a lot into your very simple question, but delving into these issues is the usual purpose of asking questions like this on an atheist website.
