You visit your loyal worshipful subjects. They kiss your feet and worship. THey write books, sing songs, and hold festivals in your honor. (Hey, you've got to admit, you love it)
But after a while you get bored, and because the new Universe is perfect in everyway you destroy the Universe and the people that you created.
You make a grand gesture with your hand (Come on, we're making a Universe here) and with a "boom", you've created a new Universe.
