The default position is: existence exists. This default position requires no creation or creator.
Any claim that deviates from the default position (such as creation occured) is required to provide a rational explanation of how it was accomplished.
In other words, explain rationally the step-by-step process of creation ex nihilo, i.e., creation from nothing. To save time, I can tell you this exercise is impossible. Therefore, only two possibilities are left then for creation: it occured by irrational, surrealistic means (a god did it), or it is a fable.
Your choice: belief in invisible magic powers or accept the truth of a fairy tale.
