If theres bad then there has to be good?

believing in ghosts and spirits doesnt necessarily mean god is real the thought of demons. demons as a concept have existed far before Christianity in cultures and religions with or with out a god(s). im pretty sure angels are too. the way we see them now are very much based in how they are portrayed in the bible and other christian media but overall they have nothing to do with god at all.

I'm not quite an atheist I'm actually an agnostic but I can see this kind of thing from an atheist pov spiritual people aren't necessarily religious people and as such it's very easy to believe in these types of entities but not a god exists as for the bad and good thing yes indeed if bad exists so does good this is the yin and yang but remember in the darkness is a little light and vice versa I also wouldn't consider every paranormal entity as bad for instance ghosts are often more tragic than they are evil just psychic imprints playing over and over again like a movie
