First use it as a platform to teach my philosophy of Logical Utilitarian Humanism, then after I have gone through the section that states that one should not have faith, but instead rely on scientific principles of logic, evidence, reason, and skepticism I would begin explaining why various supernatural things most likely are false, ending with gods. When someone asked if that meant I wasn't I god I would say very good and ask that they follow my words, not as those of a god, but as a man and see how many stick around. Then again if I was a little less moral I could always follow through on my plans when I was voted most likely to become a evil genius and conquer the world in middle school, which was to start a religion called Azerath-Kalisun Feliate Dannam Ozou pe Merein or Lord Azerath's (Literally Azerath who is the greatest among us) Sacred Truth and Duty, dedicated to the worship of the Lord of Angels (called the Astirininth) and me as his prophet upon Earth, which is one of eight worlds inhabited by humans. I created langues for various factions, idealogy, backstory... I really should right a book using it sometime. Another fun option is to claim to be a disguised Odin the Wanderer and convince people to worship the Aesir and Vanir from Norse myth.
