Civilization.
Specifically refers to the social and cultural forms and states of existence in a particular region during a specific period.
The definition of civilization is rather ambiguous, and even in modern times, debates over what constitutes civilization persist endlessly.
The only certainty is that a so-called civilization is inevitably a social system constructed by a group of people who share the same language, culture, and values.
With the capability of an individual, no matter how great, it is impossible to independently construct a civilization. This would mean creating a system encompassing all domains and making everyone accept it as self-evident, which is far beyond the limits of individual capabilities.
"Exaggerated, sounds like a fantasy?"
Demont sneered, first pointing to himself and then to Marseille.
