If your car keys are in a place where you don't typically leave them, does that suggest a ghost moved them? Or someone broke into your house and moved them, but not anything else? Or could it be that you were distracted and left them someplace unsual? We follow Occam's razor.
When there was a suspected cause for infection and that was microorganisms that couldn't be seen, the basis for the suspicion was an observed effect, and there must be a real cause for it. The microscope revealed microorganisms exist, and do cause infection. This is how a rational mind solves problems and makes valid conclusions.
For those who claim a God exists what exactly is it they think exists? Do they follow any evidence, or any clear observed effect? No. What is it that any rational mind would assume a God exists at all to solve some problem of how things are? Nothing. The ancient needs for gods to solve "cause" problems are obsolete. The invented problems are not credible as critical thinkers reveal in these debates. Your "mystery" is clearly self-caused because you like it, so invalid as a case to consider.
As has been explained to you we don't assume things exist without some observed effect, or some evidence. Believers have nothing to offer, so we reject the propostions of any supernatural.
And you believers offer nothing. I ask believers if they have some sort of extra sensory perception that allows them a special ability to sense a God, and thus far only one believer has ever said yes. Of course he was pretty deep down in the illusion hole. But the rest offered no reason why they can detect a God while critical thinkers can't. We "just don't get it", or do we? So we have no reason to trust them, and it is more likley that they adopted an illusory belief from others, and failed to apply critical thinking to the ideas they adopted.
