The Bible speaks of the transient nature of all Creation. The human experience of, and with, life verifies this Biblical view. You need only take a trip back to where you grew up to realize how things change.
Old landmarks disappear, and the people there are strangers now.
Generations get cut off from each other by time and change. Not many people know anything about their great great grand-parents. Any idea of permanence we may tend to attach to our own lives is diminished when we remember the dusty bodies of friends and loved ones who did not last very long. When we understand the frailty of life, we begin to realize that whatever we want to do, we must do quickly. We are not here for long.
