What evidence??? When we die we don't just go away. Our physical body dies but our soul travels to the after life stage.
Do apes have souls? Monkeys? Lemurs? Bats? Rats? Cats? Kangaroos?
What about alligators? Frogs? Minnows? Starfish? Ants? Jellyfish? Sponges? Corals?
Plants? Fungi? Amoebae? Archaea? Bacteria? What about a bubble of lipid with proteins inside it?
Life evolved from chemistry, and
is chemistry. Chemicals don't have souls. Your consciousness is the result of complex biological phenomena, and when those phenomena stop, so does your consciousness.
Not convinced? Well, in my previous post I mentioned memories, thoughts, consciousness and personalities.
1)
Memories. This is the easiest one. We've all forgotten things, for one. We've all met people with dementia who have serious, permanent memory issues which can be traced back to a neurological cause. We also know that brain injury can cause amnesia, especially injuries to the temporal lobe.
2)
Thoughts. Our thoughts are contained within our brain and are the product of evolutionary processes. That's why we have so many irrational thoughts, and why our thoughts can be affected by both disease (whether that's depression, or dementia again, or any other mental illness you care to name) and by medication. Again, our thoughts can be affected by brain damage. Look up Pick's disease, or reduplicative paramnesia, for instance.
3)
Consciousness. We can differentiate between a number of disorders of consciousness: brain death, persistent vegetative state, coma, and most crucially, locked-in syndrome. In the last of those, despite the patient
appearing to be dead due to their inability to move, they retain consciousness, which can be detected on brain scans, including responding to questions. Consciousness is located in the brain.
4)
Personalities. I mean really we've already covered this, but again diseases of the brain like Alzheimer's and Parkinson's affect personality, as do some brain injuries. Conditions like prenatal alcohol exposure have predictable impacts upon personality.
