Question

[GrandizerII]

Need to fix my words here is strong. What I should have said that you won't convince me that your Christian god exists, unless some vivid explicit miracle happened that was clearly from that god and everyone I know and trust witnessed the same thing and couldn't arrive at any other more plausible conclusion. This does not mean that I would necessarily go back to the Christian faith, only that I would believe. It's one thing to believe a god exists; it's another to want to acknowledge it as my god.

Even if that explicit miracle happened and it fell in line exactly with what, say, most Christians believe about God. Let's say God showed up and it was clearly the Christian God.

Still not evidence of God for me: The most plausible explanation was that a highly advanced alien visited earth and talked to people thousands of years ago to tell them to write a book. And that alien is powermad and wants us to think it is God.

The way I see it, a natural explanation is always more parsimonious and always makes sense. The chances of there being a highly powerful and advanced alien, thousands upon thousands of years ahead of us in technology, and capable of producing the most grandiose of illusions, is extremely low. And extremely improbable. But it still makes more sense than some "supernatural" being "outside of the universe" showing up and talking like a human.

Any being that showed itself in nature, would have a natural explanation... and the natural explanation would always make more sense than the supernatural one.

You're right. It wouldn't be conclusive evidence that the Christian god exists, but it would make Christianity far more plausible than it is now. And I mean far more plausible. But again, like you said, it could be aliens playing games with us, or Descartes' demon continually deceiving us, or we are all really Boltzmann brains, or we really do live in a simulated world, or we happen to live in one of those universes where Christianity just happens to be true in a naturalistic manner (e.g., Jesus did rise from the dead, but only because particles were fascinatingly arranged in such a way as to lead to such an outcome). Only Odin knows.
