That is how science works. They have a theory until it can be proven wrong by another theory. Unless if that theory goes against precedented science so you gotta destroy the evidence. Thanks Smithsonian.
best method is to never explain it. keep it as vague as possible and let readers come to their own conclusion and argue in the comments, driving up your engagement.
Jemini's stuff is not as detailed as some other system novels. I read a novel where there were 12 types of elemental magics. Each fairy could have not one but several types of magic and that defined their race. I think that would mean there could be 12 factorial types of fairies, each with their own specific name.
