Lyric discussion by Toronodo 

Cover art for Age of Man lyrics by Greta Van Fleet

It's about the evolution of society. The world changes between dark times and good times. During the dark, there is a light. The children grow up as the torch of knowledge is passed and they become children no more. They are now the leaders with no one to lead but themselves as they follow the love that is instilled in their hearts.
