Here theory was use I think a recap of the meaning of theory is in odyer.
In common usage, people often use the word theory to signify a conjecture, an opinion, or a speculation. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality.
But it is obvious that in the posts you are quoting, the term theory is
not given its common useage meaning, but its scientific meaning. That is: a theory is the the accepted best possible explanation of the facts.
