I think you are presuming the consequent here. It may help to strip the story of all emotional connotations and just treat it as a logical game - hard to do tbf but it would help. So like, if you start with a story where it is a given that a real God exists, then a lot of freaky stuff can happen downstream from that... bc the Truth is just stranger than fiction, I mean regardless of this stuff even it just is.

e.g. in The Matrix movie, you can go your whole entire lifetime and never once see The Architect, nor anyone you've ever met or even heard of either... and yet he exists all the same. Saying like "well then why have *I* never seen him" represents an assumption that may not be valid - in that case, that you would or even could ever do so (by what, walking to work, eating noodles, drinking at a pub, reading a book, intoning a chant in an old language?).

Anyway I cannot prove the existence of God so I'm not even trying to do that here, just to show you a peek into the idea that presuming that He does not exist in the first place relies on some heavy assumptions, that cannot be proven. Or maybe I'm making a mountain out of a molehill here, and misunderstanding you, especially if English isn't your first language. But those are some thoughts that I can offer to help get you started on your pathway to better understanding it from the outside, just in case they may help.
