If all of the mass-energy of the universe is added up, the total is 0. That's right - zip, nada, zilch. That is because the gravitational energy is negative and balances the positive energy of matter and radiation.
If that is the case, then not one thing was 'created out of nothing' in the way that you mean. As has been pointed out, particle pairs pop in and out of existence all the time. That is not creating anything because they precisely offset each other. And there is no net loss when they annihilate.
As Krauss and others point out, 'nothing' is unstable.
But were not talking about the universe are we? We are talking about before the universe existed. Unless you are saying that you accept by faith that (since there is no evidence) the state of the universe now and whatever the state of existence was before the "big bang" are the same.
I am making no claim whatsoever about the state of things before the Big Bang. I don't know what was before the Big Bang, or even if 'before' has any meaning in that context.
I am pointing out that we have evidence that what looks like creation ex nihilo isn't necessarily. So we have a reasonable basis on which to theorize about the Big Bang.
There is no evidence that magic is the answer. Magic has never been the answer to our questions about the universe. Not once. Not ever.
So it is not reasonable to assume it.
Skepticism is not a position; it is an approach to claims.
