Shakespeare wants to render a message through his poem, the seven ages of man that men and wowen are merely players in the drama of life. they are termed as merely players because no one lives forever but plays his/her part and departs. at birth, they enter a stage and during death, they leave it. man passes through seven phases of life in accordance with their age.
All the world's a stage" is the phrase that begins a monologue from William Shakespeare's As You Like It, spoken by the melancholy Jaques in Act II Scene VII.
The speech compares the world to a stage and life to a play, and catalogues the seven stages of a man's life, sometimes referred to as the Seven Ages of Man: infant, schoolboy, lover, soldier, justice, pantaloon and old age, facing imminent death. It is one of Shakespeare's most frequently-quoted passages.
