>>27503>everything that begins to exist has a cause of its existenceThe cosmological expansion only indicates that the same atoms that make up our universe were always there, It does not suggest they magically appeared or that there was "nothing" like the mentally feeble claim.
If Big Bang starts at a point where all the atoms exist, then it is still our universe, just in a different form.
If your new theory is that our universe was somehow "nothing" before the big bang, then you have all your work ahead of you.
