The answer is: Cain

Gen 4:17

In the book of Genesis, we find Cain undertaking an extraordinary feat following one of the most notable family tragedies recorded in Scripture—striking down his brother Abel. Due to his actions, Cain became a wanderer, but he soon settled in a land east of Eden, where he birthed a city and named it after his son, Enoch. This detail might stir your imagination as it's one of the first depictions of urban life in the Bible.

Building a city represents a substantial shift from the pastoral lifestyle that characterized early humanity. It embodies not just construction, but community, governance, and even civilization itself. The idea of creating society is prevalent throughout the Bible, unfolding into a rich tapestry of parables on communal life and personal responsibility. Also, the name "Enoch," meaning 'dedicated or trained,' echoes in biblical circles, being remembered giddily by readers for its association with later prophetic figures.

Interestingly, cities have long been symbols in the Scriptures. From the important role of Jerusalem as a divine city to the portrayal of Babylon as a product of human pride, the urban environment often reflects broader spiritual principles. Cain’s act of city-building contrasts sharply with the agrarian life his parents held—indicative of humanity's gradual evolution toward complex societies. In essence, Cain's first city marks both a historic milestone in the storyline of humanity and an insightful reflection on the diverse paths our faith journeys can take!
