Life arose with chemical evolution and then developed further in the course of biological evolution (also simply called evolution). Living beings are units capable of life, so-called organisms, which include bacteria, fungi, plants and animals. Biology (Gr. "Bíos": "life") explores life or living beings, together with chemistry, another natural science. The life sciences also include medicine, agricultural technology and nutritional sciences. Life on earth requires ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), which contain information about the development of organisms. That there is life on other planets is likely, but not certain. In addition to the scientific concept of life, there is also the social and humanistic one. In common parlance, it is often simply a question of the time and age of the human (or animal) life.
life and death
As a rule, death is associated with the life of individuals, the extinction of spiritual and, over time - in the course of decomposition - also physical conditions. One speaks of a cycle of nature, of arising and passing away. People's fear of death and the exchange about it in families and societies as well as the development of power structures lead to religious ideas and regulations about a life before and after death and into technical ideas about an eternal life, as they are widespread among transhumanists . Social robots may be animaloid or humanoid in design and simulate the properties of living beings, but they are not actually mortal: they do not leave the world, they become junk. The animal's fear of death leads to flight movements, protective measures and fighting. A few living things are said to be immortal or at least extremely long-lived, such as Turritopsis nutricula, a species of jellyfish, or hydra, i.e. freshwater polyps.
Life and economy
Humans have to ensure their nutrition in order to meet their energy needs and thus enable them to survive. Hunters, gatherers and shepherds are already training traditional forms of economy aimed at procuring food. Agriculture promotes sedentarism, insofar as farmers want to cultivate their fields repeatedly and areas are increasingly sought after and occupied. Water is both consumed directly and used for irrigation. The commercial economy is determined by the exchange of goods, often over great distances, and gradually leads to the global economic world. The dealer becomes a central figure. It allows a varied life even in remote areas and harmonizes the ways and dreams of life in the world to a certain extent.
Criticism and Outlook
In ontology, philosophy poses the question of being or being and thus also of life. Natural philosophy is close to ontology and, together with the philosophy of biology, the philosophy of chemistry and the philosophy of physics, researches the principles of animate and inanimate nature. Leukippus and Democritus already developed an atomic theory and believed life on other planets to be possible. Ethics examines the requirements, characteristics and consequences of a good life and, in this context, is interested in lust, happiness and bliss. Like other disciplines, it can devote itself to the question of the meaning of life, which, however, does not necessarily make sense. Life on earth began almost four billion years ago and will perhaps last six billion before the sun goes out, but in what form is written in the stars.
