It’s worth noting that any special allegation that is used to support the alleged existence of a creator and/or maintainer of the universe, separated from the universe itself, can be reused towards the universe itself.

• “nothing is eternal” - then your god isn’t eternal.
• “actually, God is an exception” - then the exception is the universe itself.
• “the universe must have a cause” - then your god must have a cause.

And once you do it, the new hypothesis abides better to the principle of parsimony, because you’re removing some junk deus ex nihilo entity and assigning its attributes to an entity that you know to exist.
