When we visit some place in the world, we’re very much likely to walk through the visible or invisible ruins of ancient civilization or nation.
What was once bustling with the echoes of people now sinks into oblivion. All perish and then become grounds for the archaeologists to dig and find out about the cultures which have faded away.
So where we live today would become a place of interest for the future archaeologists. Therefore we’d try to be humble in our dealings toward others because we’ll also return to the same soil as our predecessors.
