Why is the Hero's Journey plot so appealing?

The hero’s journey is basically as follows. An ordinary person is peacefully going about their everyday life. Suddenly, they find an ancient artifact/ a lost message/ a call for help etc which causes them to leave their home and journey out into the wider world. Along the way, they go through trials and tribulations and meet new friends who help them in the fight. Just when the situation seems darkest, the hero saves the day. During their adventures, they grow as a person and often find love/ take on a more grown-up, responsible role in life.

This exists in storytelling from all over the world and from many different time periods. Beowulf and Star Wars: A New Hope are examples. The book Seven Basic Plots goes much more in depth about this and other archetypal plotlines. There’s a related idea called the monomyth seems to be an even earlier, more archetypal story of this type.

Why are stories about the hero overcoming all odds and coming of age so common? They’re blockbuster movies now, and probably our ancient ancestors sat around a fire telling this storyline. Why do we like it so much?
