One key factor that sets living things apart is the presence of purpose. Non-living objects lack purpose, whereas living organisms, ranging from single-celled amoebas to plants and humans, all have a purpose in life. This purpose revolves around growth, multiplication of cells, and the nurturing of offspring to ensure the continuation of life. This concept is scientifically known as teleonomy. The question arises: Why can only living things fulfill this purpose? Living organisms rely on external energy sources to fulfill their purpose. For humans, this includes the air we breathe (oxygen), water, food derived from the Earth, light, and heat. These elements are also required by other living beings. For instance, plants need water from the Earth, sunlight for photosynthesis, and gases to survive. We expend energy to fulfill our life's purpose. If gro...
