Sometime ago I remember seeing in a documentary some women and men worshiping rats in India thinking that, those rats are death relatives...Some even think that cows are also reincarnations of the death....

There is no life after death not does reincarnation exist.... The soul is not an immortal being that exist outside the body when one dies...instead the soul is the body the flesh and so in consequence is mortal and dies....When a human being dies it returns to the elements from which its body was taken dust....For dust all living things are and to dust they return when the force of life its taken and entropy becomes the force of death....

Before you were born you did not exist, and when you die you simply return to that state of inexistence...life in its most elementary meaning is simply a momentary now surrounded by two very long eternities of unconsciousness the one before you were born and the one after you die....
