Genuinely doing this sincerely is among the reasons I stoppped believing in my mid-twenties. That is to say, though I always had doubts I was already a believer back then, but went through an extended period of analysing the basis for my faith. It sort of culminated with the realization I could never fully convince myself and stop doubting without something concrete and compelling.
Spoiler: nothing happened. God didn’t reveal himself.
Now it’s your turn to rationalize why it didn’t happen with some ad-hoc story you can’t substantiate and will almost certainly be false.
