From the very same wikipedia
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. True descriptions of reality are more reflectively understood as statements that would be true independently of what people think about them.
NOT NECESSARILY BASED ON FACTS. REGARDLESS OF US HAVING FACTS OR NOT, IT'S STILL A THEORY, DIPSHIT.
