The show probably says more about the 1970s than it does about the some unknown space voyaging race of humans.
The show starts with a narration that live on earth might have began somewhere on another planet. Immediately afterwards we’re treated to scenes of an armistice that’s been achieved with a race of self-aware killer robots. Only the peace treaty is a farce and the robots launch a surprise attack on humanity in attempt at genocide. One sole surviving space warship, the Galactica, survives and ends up leading a rag tag fugitive fleet of civilian ships on a quest to find earth. The entire series tells of their struggles to outrun the robots and survive.
