And who knows, with all that dark matter and dark energy shit, can we really say for certain that a soul isn't something that we cannot measure just yet?
The thing about dark matter is that we know it is there by inference. We can measure its gravitational effects on the rest of the universe.
But souls? There is zero effect that we can measure anywhere. Not directly, not by inference, nothing. If they were an energy, chances are we could measure it. The kind of souls that transcend the body are just made up.
