Here's my simple, intuitive proof that souls must exist. I think it makes a lot of sense, would be curious for feedback: Very simply, why does our physical brain happen to be the brain that generates our particular consciousness? It's a very simple, elegant question that goes very deep. If science explains consciousness as a byproduct of the brain, but science says NOTHING about why our particular brain generates our consciousness, rather than another brain, say the one of your neighbor, colleague, or boss. So if this is true, there must be some CONNECTION between our physical brain and our consciousness. There must be some force that connects our physical brain to the consciousness that we experience. Sure, even if science postulates that the physical brain generates consciousness, it says nothing about why our consciousness had to be generated by the brain we currently have, versus another brain. There are 6.5 billion human brains out there, why couldn't my consciousness have been generated by any other one of those brains? I think this is strong proof that there is some other force out there that connects consciousness to a particular brain. We may not know the mechanisms yet, but this force has to exist, in my opinion, and I believe it is a very strong argument in favor of the brain / consciousness duality and the existence of a separate soul outside of physical body. What to you think?
