The fact that you wished for something is born out by the fact that you posted. Even if your post doesn't bear out what you wished for, it probably comes close.
Even the animals have personal identity. How can you tell? There are no two of them that are exactly alike or exist in exactly the same space. However, if you mean soul or spirit, that is something that even science is proving. You are going against the grain of history and recent science if you say there is no soul or spirit.
As usual, you are not making any sense. What does personal identity has to do with made up concepts like soul or spirit?
And you obviously aren't following any scientific research if you think there has been any sort of proof for those vague concepts.
Claiming that i am going against history is just weird nonsense. If you are saying i don't hold much value on belief systems people used to have, that's true.
As history is full of weird belief systems that don't make any sense. They were used to understand cause and effect, and not they have been mostly replaced by scientific method.
