If it wasn't fiction? Here's the thing: I might be open to the prospect of a humanoid 30-something white guy talking to me being an apparition of God. But I really don't get hung up or terribly passionate about things like all the laws in Leviticus, or whether certain stories are 100% literal or metaphors. Maybe I'd ask, but it wouldn't impact my faith one way or the other, really. And if it turned out that the guy who said he was God was just a telepathic, shape-shifting alien? Meh. A lying alien. Big whoop.
It's not a telepathic, shape-shifting alien, it's an omnipotent alien that created the universe and implies that there is no reality higher than this. Would that impact your faith? Assuming for the sake of argument that he's not lying, would you think that a) he's God, b) he's mistaken, there's a higher reality over which God presides or c) there is no God.
If it runs counter to what my beliefs are, I'd assume he was mistaken, but it would certainly put some kind of perspective on how my God went about things.
I am not the type of Christian who forces the issue on others, but I find debates of Christian canon interesting if trite, and all too often tantamount to trolling. I really don't assume to know how we got here, and whether the universe as we know it was actually wrought from nothing over the course of 168 Earth hours, or whether it was "steered" by some higher power over trillions of years is not something that matters too much to me. Therefore, the mechanical minutiae of said creation matters even less.
The fact is that we are here, and that's a mysterious and wonderful thing!
