Efreeti are the primal spirits of fire. They predate gods. So, while we're pulling up BS math, Primal spirit > god.

And Rubah, it's not conclusive, but there's decent change Shiva was based on the Slavic Siva (AKA Ziva, AKA Shiu-wah, though that one's apparently fallen out of use), or at least blended with the Hindu one to create the one we meet in FF.
