What I meant is that QM does not describe space, it describes the behavior of sub-atomic particles in space.
I would say that QM describes the behaviour of quantum objects and their inter-relationships – it makes no assumptions at all about either space or time.

Since it does not describe spacetime, it does not account for all the entities that exist.
You are suggesting here that spacetime “is an entity which exists”?
I suggest that spacetime does not in fact “exist”, except as a manifestation in your mind/consciousness. “Space” and “time” are the concepts you have constructed in your mind to enable your consciousness to understand (to assimilate) the fact that quantum objects are inter-related with each other in configuration space. I suggest that neither space (your concept of 3D space) nor time has any meaning, let alone existence, in the absence of such QM inter-relationships. Hence spacetime is an emergent conceptual property that arises form the conscious attempts to interpret and understand the inter-relationship of quantum objects.
Think on this – the ultimate quantum object is not a sub-atomic particle, it is the wavefunction. What we observe as the behaviour of sub-atomic particles is simply the manifestation of the wavefunction which describes them. The wavefunction evolves completely deterministically, and exists NOT in any spacetime but in configuration space – the configuration space of all inter-related quantum objects.

If it did, I would say it would be the Theory of Everything.
I do not personally believe that we will ever have a ToE, but that’s my humble opinion and a completely different topic.

I'm not saying that spacetime isn't in some sense quantum mechanical, as I believe spacetime to be descrete, just that its not described by QM, and thus can't be used to justify the existence of the universe from nothing when it can't explain the two most fundamental (from our limited experience) aspects of the universe . . . space and time.
Spacetime is not quantum mechanical, it is a mental manifestation constructed by your consciousness to enable you to make sense of the configuration relationships between QM objects. As such, QM does not need to explain or describe spacetime, since it does not depend on spacetime.

Yes, time simply is a degree of freedom in 4 (or more) dimensional spacetime. But don't make the mistake of thinking that anything 'moves' along it.
Thank you for your advice. No, I don’t make this mistake.

If somethings there, then its there. Sure, it could all just blip into existence and out again just as fast in an uber-objective sense, and we would experience no difference at all . . . but your left with an over-arching framework of time to explain.
The explanation is simple – time is part of spacetime and spacetime is simply your conscious attempt to understand the configurational inter-relationships between quantum objects. It does not exist outside of your conscious mind. That’s it in a nutshell.

I totally agree with Pi about the word multiverse. At first it had a neat sound to it, but after a while it doesn't have the definitive all encompassing sound and impact that universe has.
A rose by any other name…… what’s in a name?
"When I use a word," Humpty Dumpty said in a rather scornful tone," it means just what I choose it to mean -- neither more nor less."
"The question is," said Alice, "whether you can make words mean so many things."
"The question is," said Humpty Dumpty, "which is to be master -- that's all."
