Where do space, time and gravity come from?

Roger Penrose came up with a very plausible theory that the heat death of our universe looks like the big bang moment, from the perspective of a photon. So our universe is caught in a cycle of birth death rebirth ad infinitum.

iirc the CMB clues he’s talking about to justify the CCC have been ruled out.

While Penrose's specific theory is probably not correct, it does provide a conceptual framework to imagine how such clues might be possible.

but what created that loop in the first place?

There isn't a logical rule that says everything must have a beginning.

For example, do you think it's necessary to ask what created the natural numbers? When did they begin existing?

That question makes as much sense as asking “but what will be destroying the loop?”.

It's possible that there never was a first place.
