Is It Impossible to Be Annihilated?

There's some sense in which you might think that it's impossible to be annihilated so depending on our theory of time if we take the view that the the past hasn't existence. You are always indelibly marked in a block universe as having had a certain existence and that existence is there for eternity. i wonder whether that that plays any role in our evaluation of our lives if we think that in some sense we are there indelibly and cannot be totally annihilated. It may just be that what you mean by annihilated is perfectly compatible with this it means that for example your opportunity for generating for the meaning maybe maybe ended.
