"Multiverse" theories provide for universes (including our own) to be "local": There is no way to escape whichever one that all of us occupy, because such "local universes" are "causally separated" from each other, with the scales of space and time differing so greatly between them that we cannot travel from one to another, either because we would not fit into those in one spatial direction from our own, or because processes of subatomic decay (that have already been observed) would prevent both us and any of our conceivable descendants (even including robotic beings into whom our nervous systems might've been transferred) from lasting long enough to interact with whatever vastly larger inhabitants they might contain. The latter is the situation characterizing the Conformal Cyclic Cosmology mentioned earlier, and the former is the situation characterizing some "bouncing" cosmologies, which are generally "inflationary", meaning that each "locality's" Big Bang is almost exponentially more intense at the beginning than it had originally been thought to be, but tapers off into the nearly inertial expansion that we see as having occurred relatively nearby (but far outside our solar system) today.
The most popular of the bouncing cosmologies may be Nikodem J. Poplawski's "Cosmology with torsion", which is described in a paper by that name, along with many others he's written between 2010 and 2020, all available free on the "Arxiv" website maintained by Cornell University: Some of them have also been carried in the printed journals endorsed by PSE.
In "Cosmology with torsion", Poplawski describes it as "an alternative to cosmic inflation", but it's generally considered to be a version of inflation, whose older and more plainly "mainstream" version depends on a field of subatomic particles visualized by Alan Guth, who, in the 1980's, greatly simplified the original Big Bang theory by postulating such a field, which would have caused the spatial expansion (the "bang" itself), before deteriorating, at different times in the different sorts of localities I've mentioned, into the subatomic particles (mainly photons and electrons) that we see today. Although the primordial "inflaton" particles would have had some characteristics similar to the Higgs boson, the chances of any one of them being observed today would plainly be extremely low.
As you mention a creation event, it would be the local big bang in the inflationary cosmologies I've just described: Poplawski's cosmology situates each of the local big bangs as occurring in one or another of the black holes for which much astronomical evidence has accumulated. (That evidence, however, only sustains the existence of the black holes themselves, not whatever might be going on "inside" them.) His theory is more complex, mathematically, than Guth's, although simplified plain-English descriptions of it may seem more plausible to laypersons, such as myself. In such descriptions, the spin of fermions materialized through the gravitational field of a star collapsing, after the nearly complete expenditure of the nuclear fuel whose energy had provided the outward pressure that had previously resisted that collapse, interacts with the spin of the much larger stellar fermions themselves, with the interaction reversing and accelerating the trajectories of the newly-materialized fermions outward to form a local universe, within the black hole, whose shape is analogous to a three-dimensional version of the surface of a sphere, and with that local universe thereafter continuing to expand more-or-less inertially, although much more slowly than the larger-scaled "parenting" local universe, within which the star that had eventually collapsed into the black hole had once formed, would itself be continuing a much larger version of just such an expansion: In effect, new particulate matter on a smaller scale is created in a reversal of processes involved in nuclear fusion, with some concentrated remnant of each collapsed star's original matter perhaps remaining at the center of its volume.
Because the Borde-Guth-Vilenkin Theorem of 2003 requires that the inflationary (i.e., almost exponentially rapid) spatial expansion (which greatly simplifies the formation of the elements in the Periodic Table) must have either occurred in a single temporal direction or in a continuous balancing between expansion and contraction, Guth's version of inflation may seem more plausible in a society (ours) that was raised with some familiarity with a one-and-only big bang, which is the concept that prevailed in cosmology from the 1950's into the 1980's. It is also sometimes (incorrectly) identified with spiritual beliefs in general, although, even in the West, at least one major religion considers that time has always existed, which is a possibility consistent with the "balancing" mentioned in my previous sentence.
