A Curious Endeavor

What is the significance of the presence of various deities as summonable creatures available to assist the player in the Final Fantasy games? Was all that talk of mono- versus polytheism in Battlestar Galactica just fluff? Is there something about the element bismuth which manifests the awesomeness of godhead to posters on 4chan? Is the trading card game Magic: The Gathering a complex system of ritually manipulable sacra? Is the animated series Tengen Toppa Gurren Lagann a treatise on mysticism? Why is Longcat so long?

No doubt you have questions like these, too.
