The four essential elements needed for life to exist are carbon, hydrogen, oxygen, and nitrogen. Carbon serves as the backbone for organic molecules, while hydrogen and oxygen are critical components of water, which is vital for biochemical reactions. Nitrogen is a key element in amino acids and nucleic acids, essential for proteins and DNA. Together, these elements form the foundation for the complex molecules necessary for life.

History of four elements of life?
The four elements of life—earth, water, air, and fire—originated from ancient philosophies, notably in Greek thought where philosophers like Empedocles proposed these elements as the fundamental building blocks of nature. This idea influenced various cultures, including Hinduism and Chinese philosophy, where similar concepts existed. In modern science, these elements have been replaced by the understanding of chemical elements and compounds, yet their symbolic representation persists in literature and art. Ultimately, the four elements reflect humanity's early attempts to explain the natural world and our connection to it.
What are the four elements that 96 percent of living things are composed of?

The 'big four' elements are oxygen, carbon, hydrogen, and nitrogen, which make up the majority of living organisms. The 'little eight' elements are phosphorus, sulfur, calcium, potassium, sodium, chlorine, magnesium, and iron, which are also essential for life but are needed in smaller quantities.
Why is earth unique in your solar system in the ability to support life?
Life as we know it requires carbon, oxygen, nitrogen and smaller amounts of other elements. Those elements are needed in particular forms. The only planet where they exist in the amounts needed is earth. The proper ratios may exist in an extremely small amount on Mars. So far no life has been found on Mars. Suggestions have been made that life could be based on ammonia or some other compound instead of water. So far it has not been found.
