Which one do you support?
Other: I use math, but I do not believe in math.
Same happens with the moon.

You need not ask the questions: what actually happened? what is really true?
you merely need to ask the question: which model yields the most accurate predictions? You are free to use any model (or models) that provide a prediction, if you get good predictions then keep using it until you get bad ones...then revise the model.
