Wrong. As a solid H2O is called ice, and even minimum wage fast
food flunkies aren't confused by an order of water that has
some in it. And there's no such thing as "water gas". It's a
vapor. Completely different animal outside elementary school
science classes, with the most notable distinction being that
if water vapor were a gas it would never rain.
Bwahahaha!
It is amazing how much error and stupidity you can pack into a
single paragraph. I was especially amused by your farrago of
nonsense about gas versus vapour, and why water in the form of a
gas cannot condense into rain.
That water can exist as a gas has nothing to do with nucleation.
As for vapor, it is a vague word that has a vast range of meanings.

Even the technical meaning is subject to numerous alternative
definitions, but the preferred one is that a "vapor" refers to the
gaseous phase of a substance at conditions below the critical point
(which is the sense I usually adopt). As such, gas is a broader category
which subsumes vapor since gas refers to the gaseous phase both above and
below the critical point.
I won't further confuse your addled brain by pointing out that it is
possible to move from the gaseous to the liquid phase without a phase
transition (so-called dense-phase effects to the left of the critical
point).
