The Big Bang theory is a theory, based on evidence from observations of our expanding universe (galaxies, etc).WTF are you talking about other universes?Our space and time may have had a beginning, but other universes may have already existed. Science doesn't definitively speak to this except for new theories being developed.
... whatever is outside of our space time envelope is unobservable. You literally can't see it or reach it.
No one knows what really happened about 15 billion years ago, and it could be theorized that other "universes" exist besides the one developed from our theoretical singularity.
All these possibilities are "natural", unless there is evidence to the contrary with "rational" concepts/definitions.
