Humans and animals differ in as much that human being posses a part of them that survives death, the part we call the soul.
Says who? there is not one shred of evidence for this.
Read the Bible, Martin, you will find the evidence there
I'm very well versed in the Bible thank you. The idea of a soul is a Greek one, taken up to some extent in the Bible, but that doesn't constitute evidence for its existence. The soul was a proposal based upon the prevailing doctrines and dogma, ideas and understandings of the time, but, just because it is a proposal, doesn't mean that they had, or could present, evidence for its existence as something apart from the functions of the brain.
Had the ancient Greeks had the benefit of modern medicine's understanding of brain function, I doubt whether the idea of the soul would have been understood as something apart from the body.
