One thing (among many) that always bothered me about JW teachings is what happens to the soul when we die. Sure God could be capable of creating a body and implanting it with all of our life experiences an memories. But how would not be a just a clone instead of being actually us? The only way to get around that is some essence or soul that exists even beyond physical death that makes us who we are, not just a collection of facts about what we observed and thought in our life times.
If technology developed to the point that all of our memories could be copied into another body, that would just be a copy or a clone. It wouldn't be us. So logically it seems there is something more there, a soul. Otherwise, no one would ever truly be resurrected. God would be creating a copy of us.
