I believe that there is no definition that can fully explain and describe life because we cannot comprehend the acts of God. But life has certain qualities that we can separate and distinguish from inanimate things. Life is taking in what is given to it and utilizing its environment to supply for its needs. Life is affecting and manipulating others in it s own environment to make and cause changes. Life is growing, maturing, learning, and developing.
Life is simply the predecessor of death.
Life has a beginning and a end. I agree that life is biogenesis that life came from life. Since life came from life the question asked is where the first life originated from. The first life was God who then gave life to have life.
