No, you are quite deluded for believing ghosts are a religious concept, not a human experience. Poltergeists, apparitions, EVPs, all have plenty of physical proof throughout history and almost never are related to religion. Yall are like the Birds Aren’t Real people and forgot wtf you’re even preaching. Atheism by definition means disbelief or lack of belief in the existence of God or gods. Says nothing about spirits, entities, the afterlife, etc. There are no gods, but there sure are ghosts. Enjoy being stupid.
