What is life?

The major Western Philosophers from the early Greek thinkers to the famous philosophers of modern times, with an emphasis on their attempt to answer the BIG, seemingly unanswerable questions humans have asked since the beginning of time — What is life? What is justice, What is happiness, Does God exist? etc.” It is a study that reflects human life, culture, trends, and ideas of the time, as well as it’s relation to our life today. Did western philosophers meet this goal? Could you please explain how, why, or to what extent it did, or did not, meet this goal?
