What is the meaning of life? A very basic question, as the issue of the purpose of life has occupied the minds of human beings throughout history. On this issue, philosophers weave theories, poets write songs, young people withdraw from society "perhaps they will find the answer," and the elderly continue to live, but they keep wondering the same question. It is clear that life is a tangible reality. No one can deny the existence of the world or the existence of human beings. You live, eat, sleep, breathe, and move. But do you understand why you exist?
