Since this is a scientific page, it should follow scientific terminology.

The word "theory" is very specific in the field of science. I recommend reading https://curiosity.com/topics/whats-the-difference-between-a-fact-a-hypothesis-a-theory-and-a-law-in-science-curiosity/.

The Big Bang has withstood multiple tests and evidence has been provided for it to have happened. In such a situation, it should not be called a theory.
