Air is not a substance, it is an idea.
Air is not a thing, it is a concept.
There is no air molecule.
Air is a container term, like water or pizza.
It's only purpose is to describe a collection of things, in this case invisible molecules.
There is already a word to describe a collection of invisible molecules: atmosphere.
The concept of air is contained within the concept of atmosphere.
The idea of atmosphere is not contained within the idea of air.
This means that atmosphere is the preferable term.
Air is simply another way to say 'atmosphere at low elevation'.
Atmosphere is the primary term and air is the secondary term used to refer to a collection of invisible molecules.
Atmosphere is the preferable term.
Air is so redundant that it doesn't even get its own Wikipedia article.
When one searches for air on Wikipedia, there is an automatic redirect to the article Atmosphere of Earth.
Here are 3 reasons to use the term atmosphere instead of air:
1. To eliminate redundancy by disambiguating these 2 terms.
2. To be freed from the misconception that we received growing up that air is a physical thing and not just an idea.
3. To perceive that we are closer to space than we thought.
Atmosphere is not a closed system.
There is no glass bubble keeping the invisible molecules close to the surface.
Atmosphere is an open system.
We are connected to space right now.
