Of course it is reasonable. Much more than making up an explanation. Because, let be honest, all theists not sharing your particular brand of god must have made her up. And you seem to found all your belief on incredulity, Incredulity that things can exist without any cause nor reason. Arguments by incredulity are a logical fallacy, that makes your all reasoning technically irrational.
So, let us suppose I also get a mental storm, some sort of mental state change, and start seeing the need of a god, or something beyond, to explain things. Which one should I choose, considering the high probability of choosing the wrong one?
I still have no answer to that.
