Viruses are not considered a form of life because they lack the cellular structure and metabolic processes characteristic of living organisms. They cannot reproduce independently and must infect a host cell to replicate. While they exhibit some traits of life, such as evolution and the ability to respond to their environment, their dependence on host cells for reproduction and metabolism places them in a unique category, often described as existing at the edge of life.
