Well I don't believe in God, and I doubt the existence of any spirit or supernatural beings. Which is why I sent GIIVideos my question. This was originally a private message that I sent on youtube, but now it's on a forum.
There is no proof of spirits or anything beyond human power. I don't dismiss the possibility because I have experienced events that I thought to be spiritual encounters, but there could also be scientific explanations for them, so I neither accept nor reject the idea.
