I asked this question before, and the discussion led me to read a book called A Confession for Leo Tolstoy (a small book of about 100 pages). His conclusion didn't satisfy me. However, it made me think maybe asking "what is the meaning of life" is the wrong question to ask. Have you wondered what is the meaning of, let's say, a butterfly's or an elephant's or a tiger's life? Have you wondered what these animals do everyday and why?
