The meaning of life, or the answer to the question "What is the meaning of life?", pertains to the significance of living or existence in general. Many other questions also seek the meaning of life, including "What should I do?", "Why are we here?", "What is life all about?", and "What is the purpose of existence?" or even "Does life exist at all?" There have been a large number of proposed answers to these questions from many different cultural and ideological backgrounds. The search for life's meaning has produced much philosophical, scientific, and theological speculation throughout history.
