Theories tend to Remain a Pseudo Fact, until proven otherwise, the theorist, is under no obligation to Prove his Theory, which makes anyone capable of writing a Theory, without using any Facts whatsoever. Of course it's always advisable to throw a few facts around within the Theory, to add some Credibility to your Theory. Remember if you could prove a theory as Fact, then it would no longer be a Theory, but a Fact.
Scientific observations and experimental results are required for a theory to be scientific.
A "theory" is a scenario of what might be.
Evolution is both theory and fact. Moreover, the fundamental theses of the theory (common descent, natural selection) are so well supported by fact that they might as well be called fact.
