So, what you are saying, is that a flat earth cannot have an atmosphere? However, the FE community regularly uses that word. So we are at an impasse. Either A: the flat earth has a atmosphere, which makes it a sphere, or B: it doesn't, which would kill all life.
Or C, it has a region of gas, a mixture of nitrogen, oxygen, argon and various other molecules, which is not in the shape of a sphere and thus would not be called atmosphere and instead be called something like atmodisk, with this atmodisc supporting life.
It is something made up, and therefore cannot be used as a scientific term.
All words are made up.
In fact, science is quite happy to do that. When they discover something new they are quite happy to make up a word for it, or allow others to do so later down the track to get it named after them.
Not having a word for it doesn't mean it can't exist.
By that reasoning, before we had a word for UV radiation, that absence of a word is proof that it can't exist.
Do you really want to try going down this path?
UV is just a made up word.
Just like IR and microwave and X-ray. I guess they are all fake as well?
That term is very important. It quantifies a theory. It can prove, or disprove.
No. Numbers quantify.
A term is just used to make it easy to recognise and talk about rather than needing a very long phrase.
It cannot prove or disprove a theory.
Have you heard of phlotegen? It was a real word. Does that prove that "theory"?
What about fairies?
That is a word basically everyone knows.
Does the existence of that word prove fairies exist? No.
your term is not searchable anywhere.
I take it you haven't heard of google.
http://www.lmgtfy.com/?iie=1&q=atmoplanea term, unrecognized by the dictionary of choice, or much of anyone outside the FE community.
i.e. jargon, something quite common in scientific discussions.
By your reasoning, my PhD, and plenty of others are pure garbage as they use "made up words, unrecognised by the dictionary of choice and much of anyone outside the field".
Grow up.
