God is so quiet

Space-time is not exactly a "concrete object" is it?
I'd describe it more as a framework upon which concrete objects exist.... a framework that can bring forth concrete objects, it seems.

I don't think so. Cosmologist do not consider space-time to have existed prior to the big bang. So the singularity (all matter in one spot) existed prior to our space-time.

Cosmologists consider that all space-time in our universe was compacted into a very small singular "location".
If any lies beyond that is unknown and no cosmologist will claim anything about it, unless under a hypothetical. Just like I'm hypothesizing that space-time (if it exists beyond our Universe) could be the origin of our Universe, the generator of that singularity.

Also, note how your words undermine what you want to say -- "the singularity existed prior to our space-time". What would "prior" mean, in your hypothetical scenario in which time is non-existent? Also, what would the verbal form "existed" mean?
My mind finds it extremely difficult to think in terms of absence of time... yours seems to be similar.

My hypothesis has the merit of retaining the temporal factor across the Big Bang so we can still think of causation and use our words and concepts.
