Your question betrays a common misconception about the Big Bang -- that is was an expansion from a single point -- a singularity -- into a large, empty space. That is NOT what happened.
Rather, the Big Bang was an EXPANSION of ALL space, at ALL points in our Universe. Every spot in our Universe was, about 13.8 billion years ago, of equal density, and that density has been decreasing ever since. The point 20 billion light years from our Earth is no closer, and no further, from the place of the start of the expansion that where we reside.
Your misconception probably arose from the oft-repeated, but VERY misleading statement, about the OBSERVABLE universe -- a sphere of radius 46 billion light-years -- being once smaller than a proton. That's true but completely irrelevent, because that fraction of the total universe that we happen to be able to see is just an infinitesmally small part of the total Universe. It's quite possible that our Universe is infinite in size, and has always been infinite in size.
Thus, our Universe has NEVER been a singularity -- and thus, it could never have had a rotation.
The Big Bang almost certainly did occur.A singularity, on the other hand - whether it is the singularity of the Big Bang, or the singularity in a black hole - probably indicates that something is incomplete in our current understanding of physics.
the singularity
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
There is not a theoretical way to determine "where" the Big Bang occurred. In point of fact,the idea of a "where" existing before time and space began hasno meaning at all. Since theoretically the Big Bang resulted from a singularity, then the where, when, how, and why ofour unfolding and evolvingSpaceTime continuum(or our traditional four dimensional universe) must be based from this pre-Big Bang singularity. You would need to approachsuch queries from the perspective of "what" isthis singularity.

A singularity, made of unimaginably dense material.
yourmom
The Big Bang Theory states that the entire Universe came into being after rapidly expanding from a singularity of infinite density.
'Singularity' ; a moment when energy exploded and matter was created.
A singularity is a point in space-time in which matter and energy are infinitely dense, as at the center of a black hole or at the moment of the Big Bang.
the big bang theory
No, it's the other way round. The Big Bang is responsible for the redshift.
