Evidence from neurology points towards consciousness being purely a process that is carried out by the brain. There is no good reason to suppose that consciousness can survive the destruction of the brain at death.
It is arguable that our physical bodies and its processes do make up a large or,if not, significant portion of what we might call our identity. E.g. predispositions (likes and dislikes, talents), gender, effects from the impressions from our social context etc.
How do you define "life" and "death"? What makes up life? your physical body, your soul and your wills? What is death? when your body stops functioning? or the eternal lost of your will?
