Eternal life - a myth or reality?

At all times, one of the fundamental worldview issues was the question of immortality, humanity dreamed of it, was looking for ways to achieve. Is eternal life possible? Is death a natural continuation of it? If eternal life is possible, then in what form of existence? Is there any meaning in immortality and does it need a person? These questions today more than ever excite humanity against the background of the crisis of religion.
