I'm God. What evidence do I need to provide?

This is all really interesting.

I have a friend, who I will call Peter to protect his identity. (His real name is James.)

I've known him a long time, although the time I've spent with him amounts to quite a small percentage of my time alive. I hadn't seen him in several years, and he suddenly turned up to visit me. Upon seeing him, I was happy beyond reasonable doubt to say that this was my friend James. I mean Peter. I didn't ask him any questions, I didn't ask for any evidence, and I didn't ask him to do anything. I just decided that based on all my previous experience, this was Peter. It's the same person.

Now, it's possible that he never was quite what I thought he was, maybe his real name is Steven and not James. It could all be an elaborate deception. However, he would still be the same person I know as Peter, whatever he may actually be. I could never say 100% he is not an alien impersonator, either this time or any previous time, but I'm still comfortable with the high probability that this is my friend.

What I've seen in this thread is that even if the real God turned up, people would not recognise it. They are apparently not as familiar with it as I am with one of my friends. They would be sceptical that this was really the being they have been worshipping all this time, even when it was standing right in front of them. They would demand evidence from their own god. This implies that they actually have no significant prior experience of their God at all, and couldn't pick it out of a lineup. However, some magic tricks seems to be all it generally takes. This means any alien with enough technology to do some "magic/illusions" could pretend to be "God" and get away with it.

I wonder how many religious theists would actually care if their God was just an alien with some magic tricks, and had no part in the creation of the universe or any power to grant afterlives? Because I've seen no argument for how they can be even vaguely sure this isn't the case. Assuming they are worshipping anything real at all, that is.

Maybe this theistic scepticism right in the face of the God of the universe might give them some perspective as to why we are sceptical about a book.
