Which plot would most likely be set in the future where Earth no longer exists?

A plot set in the future where Earth no longer exists could revolve around a group of survivors living on a distant planet after humanity has fled a dying Earth. These characters might grApple with the remnants of human civilization, facing challenges such as resource scarcity and alien life forms. Themes of nostalgia, adaptation, and the search for a new home could drive the narrative, exploring what it means to be human in a world vastly different from the one they left behind.
