freemindfade,
We used to look up and see a comet and say the gods were riding by and bringing some natural disasters... the people who didn't believe were persecuted for heresy.
I use fairies specifically because there are old books, folklore and tales that abound with them.
Just as tales, old books and folklore abound about god.
They both claim extraordinary powers and both have influenced human thinking to some extent.
As you point out sometimes things just don't make sense. (like the existence of fairies)
This is the result of humanity becoming more rational and less superstitious.
