We can conclude from the above discussion that according to the religious and non-religious historians the belief in life after death existed in the olden days and even before writing was created. This belief had existed in the pre-historic times. Every nation expressed its belief in this according to its customs and this belief was not tinted by apartheid, sectarianism, genetic control and linguistic dominance or geographical pre-eminence but was present in pre-historic and later times in general.
As has already been discussed it is a part of human nature and is not something gained externally through experience etc and did not change or does not change with the vagaries of time.
