At school (in Poland), at religious education we were taught that hell doesn't exist with all thisfire and burning. That it's simply "tthe absence of God"
Imo, there IS no heaven, hell, or spirits.
The only thing CLOSE to a spirit is our consciousness which is basically the "user interface" of our brain.
When we die, the consciousness simply stops being used by the brain because the brain is a receiver of this consciousness and thus consciousness lives on but YOU die.
The dated idea of religion to give comfort that our individuality and life will live on after death with our consciousness but even though our consciousness lives on, our person is gone because it's our brain that makes the memories and everything but our consciousness is what interprets everything.
New study says that consciousness isn't from the brain itself but, rather, the brain is like a receiver similar to a TV antenna and stuff and picks up signal which is our consciousness.
