I don't give a crap about how much u understand science. There were so many things that happened to my family that you wouldn't understand. MY family have seen demons tormenting them. They seen things come then vanish. And so have I .If they saw demons then that is a spirit. My family has seen. All of them. And many miricles has happened because we prayed for god to help us. My dad should be dead right now because his cholesterol is so thick that you can see it when the nurses take his blood.
