My own religion
I wouldn't attribute it to anything at that point since I wouldn't have anything like enough information to reach a conclusion. I certainly don't see any reason to assume anything "spiritual" specifically.
It's also worth noting that "miracle" describes something that literally can't happen, so if something we thought to be miraculous actually did happen, it would prove it wasn't actually miraculous. Similarly, if something perceived as "supernatural" turned out to be real, it would actually be "natural" (something that has happened with all sorts of things in the past).
The entire "natural" vs "supernatural" argument is really just empty semantics. The only relevant questions are; What was the cause of a phenomena or event? And; Whether we currently understand what that cause is or not?
So you know for all times as an absulture that there is no supernatural God? Well, that is not how I understand knowledge.
