What is the study of life?
The study of life is referred to as biology. It is derived from two Greek words; "bios" meaning "life" and "logs" meaning "study". Thus biology is the study of life and the properties of living things.
A very good question that could be asked is; What were the molecules that originated life? This could be traced back to simple molecules such as water, nitrogen, carbon dioxide, etc.
A careful experiment could be designed where these molecules are subjected to conditions similar to those at the beginning of the universe in order to decipher how they joined together during the formation of the universe.
