How does nature react to human life in the tide rises the tide falls?

In "The Tide Rises, The Tide Falls" by Henry Wadsworth Longfellow, nature is portrayed as eternal and indifferent to human existence. The repetition of the tide rising and falling symbolizes the cyclical nature of life and death, highlighting how humans come and go while nature endures. Through this poem, Longfellow conveys the idea that nature continues its rhythm regardless of human presence, serving as a reminder of our mortality.
