As a farmer, Kayin was in contact with Hashem. When he lost the contact, he had to rely on human intelligence that flourishes in the cities – developing science, engineering, processing produce. He also started the tradition of donor building right naming the city for his son, hoping to keep his memory eternal (paraphrasing R Elie Munk). Note that he tried to defend himself claiming that he did not know the other guy would die from the blow. As the defense did not work, he realized that not knowing science is not an excuse (my addition). Note that he started science education without ethical component (from a drasha, not sure of the source).
