The line from Bobby McGee applies, although it's intended otherwise.
It boils down, doesn't it BB, to the something/nothing argument.
We get to have something be in the eternal past or we get to have nothing be in the eternal past.
If nothing, then it gives rise to itself.
If something, then we've got to ask what kind of something could give rise to all else.
(So far as the Ladies nodding in the affirmative -- they might even have nodded a bit too quickly. :>)
Truly, we mortals fall into mental gymnastics every time we try to apply our mental constructs to God.
Time, for instance, is a property of the Creation and not something in which the Creator exists. Nor indeed can we think of Him as a thing subject to being described by space/time coordinates, volume and such. Ditto for Aristotlean Laws of Logic, e.g. Law of the Excluded Middle.
Words like timelessness, spacelessness, uncaused cause of causation would be more appropriate in visualizing the beginning ex nihilo.
To God be the glory!
