I am certain that all life is associated with cells, may it be thousands or just one. Life occurs within a time period when these cells can grow and adapt to the world around them. During this time period, organisms use energy to develop new skills and functions, like metabolism and homeostasis, necessary for survival. This energy provides the ability to reproduce and create new life similar to oneself. Life is not just some body filled with cells working together to stay alive, but the idea that this body can have feelings and share them with other living creatures.
Life is a time to love and accomplish goals.
It is, however, fragile and for some organisms it lasts longer than others. Although the reality of living is that a single life can end, the continued reproduction that life's energy provides, can help ensure that life itself will not perish. I believe, like many scientists, that life was first created by chemical evolution. These organic molecules could have collected in the ancient ocean and produced amino acids. I do think that the building blocks for life probably died and were created again many times before the organic molecules that produced life fully evolved.
