What we see now is the result. At the start the Universe was smaller than an elementary particle and the inhomogeneities we see now due to quantum uncertainty. We think. The fact that the microwave background radiation temperature is the same to one part in many thousands means at one time everything was essentially in the same place. There has not been enough time passed for information to get from one side to the other of even the known Universe even at the speed of light.
Of course the big bang happened everywhere at once because there is no 'outside' as time and space only existed once the Universe started.
It is a bit like where your lap goes when you stand up,it no longer exists.
I am sure that in the future our ideas will seem 'quaint' but at the moment it is the best we have
.
I still have a very open mind to all of this but only if a premise is testable.
