I'm watching Ghostbusters... Fun. I thought it was interesting they talk about Sumerian gods in which Gozer a god of destruction, the destroyer is the god that becomes the Puft giant.

Is that a real god or just made up for the movie? I couldn't find much info that seemed legit.

Urban Dictionary:
Gozer: An ancient, demonic, Sumerian god. Also known as Gozer the Gozerian; the Destructor; the Traveler; the Destroyer.

Did the Sumerians believe in ghosts?
