i also believe that too. there are lesser Gods or demi-Gods like the Titans, Olympians, Greek Gods, Indian Gods, Egyptian Gods etc. etc. but I wouldn't call them Gods but supernatural beings or maybe angels - God's lieutenants/generals assigned on different regions of our world.

History is very colorful with these characters that one can't just conclude that they're just fiction. Besides exorcism / demonic possession is accepted in the Vatican, so the more it shows that are other supernatural being that can be both good and evil.
