Life after life is intuitively appealing as such beleif and/or experiences are found in practically all cultures. However, this has nothing to do with love for life nor fear of death. It has something to do with the relationship between consciousness, the concept of time the concept of eternity and conceptualization itself.
Whenever we talk of an event that is to happen during some time in the future, we generaly take it for granted how we can understand the concept. However, it is actually not that trivial. Like in all of our conception, we rely on our prio experience of something closely similar. So we understand the claim that a football match will happen tommorrow because someone (perharps our moms) have ever used 'tommorrow' that way. However, we understood the 'tommorrow' here to mean that in the day after 'tommorrow', we will be aware of some moment termed 'yesterday' whence the football match happened. This conception of actuality of events is inconsistent as applied to the concept of own's death!
