If a deity appears and by hand waving divide the red sea we could measure, observe it happen. And we can test, observe what fields, forces being used. But how the heck she project these forces may take a while to understand - be magical.

But my argument was more about comparing gods to AIs, that it is an incorrect comparison. What AI perform are not magical, and we can always figure out what the AI do.
