Time is bio-logical—completely subjective and invariably emergent from a unitary co-relative process. All knowledge amounts to relationships of information, with the observer alone imparting spatio-temporal meaning. Because time doesn’t actually exist outside of perception, there is no experiential “after death” even for a plant, except the death of its physical structure in our “now.” You can’t say the plant or animal observer comes or goes or dies, since these are merely temporal concepts.
