You are your 'current' feelings and your past memories. The reason for the downvotes is that from your logic mabbo is every person who has ever existed in the history of the human species. Since every person has their own current feelings and past memories, saying mabbo would have been that person instead is a little meaningless.
I don't understand how people can adopt this line of reasoning, can you explain? Do you think that there's a store of consciousnesses somewhere, and they're reserved/assigned?
