I've heard about a theory that the quantum physics could prove our consciousness can survive in some other dimension after we die. Since my knowledge about the quantum physic is next to nothing, I reserve my judgement. Still, even if it's true, I wouldn't call it a "soul".
Doesn't sound right. We couldn't even really verify that theory, either. Our brain is nothing more than a very complex biological computer.
I don't think there is any soul at all. Once we die, that's it. There is nothing more. Your memories, thoughts and being cease to exist. A hallmark of our sapience seems to be the thought that there is
more, that somehow we are special and not just a bag of meat with a computer in our heads giving us the reality we perceive.
Sounds sad and/or lackluster, but all scientific evidence points to it.
