Assume a world represents a universe, and within this universe are billions of stars and multiple times more planets than stars. Then, even if the probability of a civilization arising is only one in tens of millions or even billions, the number of civilizations would not be small, with at least four to fifteen existing in one galaxy.
However, not every civilization has the qualifications to reach the end. For the universe, the existence of civilization is just a drop in the ocean, but for that civilization itself, it is already long enough.
Take humanity, for example. Ever since the dawn of civilization, this race seemed to be protected by gods, but even so, it faced crises many times, nearly failing to emerge from the whirlpool.
