What if all the Gods/esses are real?

Just a funny thought. Imagine if all deities from every religions are actually real. YHWH, Zeus, Odin, Ra, Astarte, Athena, Freya, etc all exist and govern their own people in their own respective region.

While avoiding to fight each others and show Themselves to people in general, each Gods try to expand their influences through Their people so there comes competition among Gods to claim as many followers as possible. Till nowadays…

Any opinion about this silly idea hypothesis?
