God and the Multiverse

Below is a quote from the Mindscape presented by theoretical physicist Sean Carroll. Here, two physicists, Carroll and Leonard Susskind are discussing the fine-tuning of parameters and the existence of the multiverse.

Was emergent spacetime fundamental at the beginning of the universe?

In one YouTube comment thread one atheist has remarked that it is really infuriating that all the apologist arguments that he has seen presented so far have ultimately failed to provide any proof for the existence of god. All their arguments are nothing but playing around with definitions of words and literally just throwing an explanation into the gaps of our knowledge, thus showing that every single god argument is essentially a god of the gaps argument, or that they feel good or special by being able to give that argument.

Is there any spacetime outside our universe

From special theory of relativity we come to know that matter and energy are equivalent. And from general theory of relativity we come to know that space, time and matter are interlinked and that there cannot be any space and time without matter. As matter and energy are equivalent, so we can also say here that there cannot be any space and time (or spacetime) without energy.

Dr. Sten Odenwald has provided the following information on behalf of NASA Astronomy Cafe, part of the NASA Education and Public Outreach program:

Implications of Emergent Spacetime

If an entity is emergent, then in general that will imply these three things:
1) The emergent entity cannot have any existence prior to its emergence;
2) The emergent entity (A) cannot emerge from just anything or everything or nothing; it can emerge from some particular entity or entities only (B); and
3) B must pre-exist before the emergence of A.
