Fiend God
By making such a demand, who is the God, and who is the student?
Let me put it this way: if you created a universe with intelligent, rational beigns, and you, for some reason, wanted them to believe in you, what would you do ?
Would you just let them figure it out for themselves, which, considering the universe you've created is indistinguishable from a random quantum-fluctuation god mad; OR, would you actually provide them with clear indications of your existence ?? I'd go for option B.
