Not as it was implemented in Humankind, which essentially allowed you to do nothing but Prepare and explore the map u ntil you plunked down your first city - an extended First Turn, basically.Do you mean a nomadic period?
Otherwise, this is basically why I often play Terra.
Rather, what is needed is a mechanic that makes it possible to advance before you plunk down that first city instead, as now and forever in the Civ series, having you utterly handicapped until you get your first city - without a city you have essentially no Science, no Production, no Culture, since all those resources are tied to Cities.
Given that earlier groups going back to at least 10,000 BCE were either wandering hunter-gatherers or smaller-than-city Settlements that occasionally reached Near City in size, we need a way to make both of those Playable, at least for some time in the early game. Obviously, IRL nomadic/pastoral Civs became non-competitive after the Renaissance, since you couldn't put a factory on a wagon, and hunting and gathering was non-competitive with domesticated animals and agriculture so that smaller Settlements gave way to Cities. But it shouldn't be necessary to make those transitions on the First Turn to stay in the game.
