Why are artifacts such as the one shown considered indicators of a civilized community?

    The setting of the story can help to develop the theme, by showing that though they are in the same setting, not everything stayed the same. His friends had completely changed, they were all grown up with families and things weren’t like the old times. His old friends kept making excuses to leave.  "Good," Mikey said. "Enjoying this get-together, though I'll have to get the kids home soon.” And his one friend didn’t even go by his nickname “squid” anymore. This is how the setting helps to develop the theme of the story.

Not very proud of this one, sorry if it doesn't get a 5/5 grade
