Life, human life, human life. Until now, science has not been able to explain where humans come from and where they are going. If human life is compared to the infinity of the universe, it is not as short as a meteor in the sky, passing by in a flash. If you count it day by day, twenty or thirty thousand days will not be a long time. A person's life goes through stages such as birth, growth, starting a family, starting a business, retirement, aging, and death. If normal, the time is about seventy years. Of course, some people cannot complete these stages, and various reasons may cause them to die prematurely at a certain stage.

Nine times out of ten, people’s lives are unsatisfactory, and they are all pursuing and frustrated. Human life is diverse. Some people's lives are very mediocre, some people's lives are sinful, and some people have made varying degrees of contributions to the progress of human society in the fields of science, art, politics, religion, etc. .

Tradition and custom have always recognized and praised those who have made contributions to society. This life of recognition and praise should be a valuable life. In this sense, the value of life lies in dedication and contribution.

As for the significance of human beings relative to the universe, this is a very vexing question. Think slowly.
