@Kielicious,
I sometimes study a bit of music. If you talk to a musician about keys, or flat and sharp, it may not mean the same thing to them as things you unlock doors with, or the opposite of blunt.
This does not make musicians eliteists in my eyes, but they require their terms in order to describe things which make sense in respect to their craft and the philosophy behind it.
I don't think it makes scientists eliteist to point out that when they use the term "theory" it means something more important than "fact" or "observation" - just in the same way a musician uses the term "key" to mean a collection of tones rather than something that opens locks.
It is actually the facts and observations that are under greater suspicion - if you will - because they can be subject to exception, or generated via subjective processes, or whatever.
For example: the fact that carbon dating the shells of sea creatures gives wildly innaccurate results does not impinge on the general body of knowledge gathered by carbon dating - because the method by which certain animnals ingest carbon throughout their lives is understood.
In actuality, when facts are shown to be at odds with the theory it is usually a pointer to scientists to look at the facts and see why they are causing the abberations - it's usually something to do with them rather than the theory itself.
I'm with Kielicious in thinking that "theories" such as flat earth or aether are "theories" in the colloquial sense - not theories as understood by science like the theory of evolution or the theory of gravity. However, it may be that there have been scientific theories that have been overturned since Galileo's time - but I honestly can't think of one. Even if a few have most have gone on to become significant bodies of nderstanding, and to say they have become myths is a wildly misleading claim.
In fact, scientific processes feed the majority of people on this planet, and provide ever better healthcare. I myself have been saved by science on the operating table twice. Despite it's occassional misuse, I think it's pretty ungrateful of people to treat it as some blundering innaccurate process - let alone a "myth".
