I'd imagine it's a bit like how celebrity culture is nowadays. Tabloids and pop-culture are full of stuff about the daily lives of various actors and musicians, and it's literally the only thing some people know how to talk about, but the average person never meets a celebrity in their life. People in the World know full well that Gods and the supernatural are real, regardless of not usually seeing it face to face. They take it on faith the same way we take it on faith that anything else we see in the news isn't a complete fiction. And just like ours I'm sure the World has it's share of conspiracy...
