Life and death are two aspects of life, which attract diverse opinions between the scientific community and across the mainstream, religious ideologies. Christianity as a religion talks a lot about death and life after death and even embraces graves and cemeteries. Jews and Muslims, on the other hand, view a dead body as profoundly contaminated. While, across the numerous religious doctrines, the dead are either perceived as holy or distasteful, what exactly comprises or can fit the definition of death is not agreeable. However, the standard way in which one can define death, is from the perspective of life itself.
From the above approach, death is seen as a termination of life or a transition to another form of life. In the former approach, there is no continuity of life as is the case with the latter. This makes one to explore scientific view of this issue which in contrast to religious views based on doctrines and beliefs, science builds agreement across cultures, religions and races through employing rational thinking. According to science, the natural laws of the universe are the ones that shape our appreciation of life, death and the universe in general and not any culture or religion.
From a scientific perspective, the meaning of life is to comply with the Second Law of Thermodynamics through increasing entropy. Entropy is a measure of disorderliness, which is increased by most human activities like cooking, eating and so on. Death, science explains, occurs because the human being just like plants and animals possess inherent death genes which they inherited from their respective ancestors during evolution. This asserts that death is a programmed phenomenon occasioned by death genes. Science argues that the concept of life after death is raised because of the denial by many people across the world that death is destruction of the human life.
