What is required for the concept to actually seem reasonable to the mind, is a belief in what is called "Soul Sleep".
The problem for the J.W org is that because they do not know how to read the Bible in a Scholarly way, i.e, using proper exegesis to understand the writers thoughts, and take it all as literally as they can, they claim that as it says the Soul dies, that nothing of you lives on after death.
The idea that Big J contains in his big brain every one of your memories, which is pretty embarrassing in my case if true, still does not cut it as to believing that the newly created human is still really you, of course it would not be.
The usual muddled, ill-informed thinking here from the J.W org.
