Death: initiation or oblivion of consciousness?

The question of death accompanies a person throughout his life, is his antonym. The problem of the mortality of human beings always raises an eerie interest, the basis of which is, without doubt, the question: what about beyond death? - whether continued existence, or immersion in nothingness. Confirmation of interest in this problem is observed in all societies at different levels of their development, and expressed this interest primarily in the religious outlook of peoples, ethnic groups, etc. At the same time, the level of scientific knowledge of a society is irrelevant, since science can only partially try to outline the problem of death.
