It's pleasant to think souls exist since it implies that a person continues to live after they die, but I'm afraid not. It's very difficult to prove that something does not exist when there is no evidence that it does, so arguments against are actually rather ludicrous. The soul has never been observed, weighed, smelt, heard, or seen. It has never affected any physical phenomenon, and empirical evidence, mathematical or physical, that it is extant has never been found despite intense efforts to do so.
It's much like Santa Claus...A comforting thing to believe in, but every sense we possess indicates that he doesn't. Like Santa, believing that you have an immortal soul is great for children to cling to, but adults, quite reasonably, put him aside. Very few adults would accept the idea that werewolves or vampires exist; they scoff at the thought that a Blue Fairy exists who give puppets life, but they still buy into the existence of a make-believe presence.
I have often wondered why Christian theologists insist that there is a continual battle between their ''good' god and their ''evil'' god for possession of these imaginary items. Is there a general feeling that this ''soul'' is some sort of divine currency? Can souls be used to purchase some mysterious presence or ingredient? What happens if one god gets more than the other? If a soul is spent, what happens to it?
The soul's lack of existence proves itself.
