Compare the 2 paragraphs on The mythology of things that seem to be what Ifrit means by way of mispelling with the Wiki page of Shiva, and I have a feeling that the question turns into Superman vs. Mighty Mouse, proving my theory.

I mean, I'm not going to argue that the gods aren't made up, or that Shiva is somehow more likely to be a real and not made up god than Ifrit is, but I can definitely back up that Shiva has a foundation made up of solid history, religion and mythology, while, again, Ifrit seems to be a failure of communication of names. Also- not a god character in mythology. We know that god>jinn
