What is a soul ? If it’s the me inside my body, then we know as Modern humans that personality is in the brain. Do you feel uncomfortable with that? Think a moment on where your feelings come from: millions of years of animal’s evolution. Animals know a lot about practical things, like where to find food & how things fall. But the food we eat now comes from supermarkets & we know now why the moon doesn’t fall. Same thing with there being no souls for humans or animals. It’s weird but we’ll get used to it.
