The lifetime of a human being is measured by decades, the lifetime of the Sun is a hundred million times longer. Compared to a star, we are like mayflies, fleeting ephemeral creatures who live out their lives in the course of a single day.

Carl Sagan
About This Quote

The life of a human being is a lifetime that can never be measured, but compared to a star, we are like mayflies. We live in a single day and then we die. The Sun is a star that lived for millions of years before it died. It has been burning for over 5 billion years and will continue to do so for another 5 billion years.
