They are the languages used by most English speaking and German speaking mathematicians in this world.

In every standard set theory, one cannot have a set at all without having all of it. Thus whatever WM allows to go on in WMytheology is not any form of set theory.

Not outside WMytheology.

There is outside of WMytheology. If there is an unambiguous rule for telling whether a test object is a natural nor not, then there is a set of ALL the objects satisfying that test. At lest everywhere outside of WMytheology.

Only if one includes 0 as a natural, as in the von Neumann naturals.
