No, I dont believe in angels any more then demons, or shills of god anymore than witches. I dont understand what you mean by atheists inventing angels. That makes no sense.
belief in angels tends to support religious belief, why would atheists make that up?
to Brenda, how do you know there are two types of angels and not 3 or 4 or 100? Why not one type, since there's apparently one type of god?
