My belief is complex and would take a long time to explain but in brief, I believe that we have a creator but its not the God described in any religion. That God is too unethical. I belive there is a Great Spirit, lesser Spirits, Souls, demons, and ghosts. Spirits enter living things at birth and their energy creates a Soul. Souls develop to be good or bad people. Good souls can reincarnate into new life at inception but bad souls cannot. In order to survive, Bad souls must attach themselves to people, draining their energy eventually making them bitter so when they die they too become Ghosts. Demons are very bad ghosts who have created many ghosts.
I see that you are very religious and there is nothing wrong with that. Reigions were intended for good, unfortunately bad people use them to corrupt society. I simply do not like religions because they encourage favoritism, which on a macro level is the source of most of the worlds deadliest conflicts.
