There are as many notions of nothing/everything that there are notion
of things.
"Nothing" can be interpreted in many ways, differently for each theory
candidate to be a theory of everything (ontology/epistemologies).
The everything idea in this list is that conceptually simple theory
are preferable than complex theory, but conceptually simple theory
tend to multiply the possibilities and the ontologies, and the taking
into account of the first person view entails such possibilities
interfere.
Comp explains as most as possible why there is something rather
nothing. UDA makes elementary arithmetic enough, and elementary
arithmetic can already explain why you can't get them with less. So
our belief in {0, 1, 2, ...} is mysterious, and *has to be*
mysterious. But then we have the explanation of the emergence of
quanta and qualia from {0, 1, ...} and the + and * laws.
Any first order logic specification of a Turing universal system would
do. The key discovery is the discovery of the universal numbers, and
the ways they reflect themselves in the arithmetical truth/reality.

If you insist on the strictest definition of "nothing" which is not
even the potential of producing anything, then even God Himself
could not produce something from nothing; and this line of thought
is quite clearly leading precisely nowhere.
At the meta level of a theory, "nothing" and "everything" are
basically equivalent with respect to the difficulty to be define
them.
In set theory, everything (the "universe" of set) is given by the
unary intersection of the empty set, for example. And the quantum
vacuum, needs the whole non trivial assumption of quantum mechanics.
The "no" and the "every" in "nothing and everything" depend on the
logical assumptions. The real difficulty is in the definition or
choice of the notion of "things".
