I wonder if living in the city makes it easier to believe in humanism.
Humanism is described as “an outlook or system of thought attaching prime importance to human rather than divine or supernatural matters.” 
You are surrounded by the accomplishments of man, all that man created.
Is it easier to see and focus on the surface level and declare that God doesn’t exist because you see the great things mankind has done.
Is it easier to forget to ask the deeper questions: “Where did that material come from to build these great things?” or “Where did man who made this stuff come from?”
China (and many other parts of the world) are moving into cities. A study of the demographics will show you that people are moving into the cities and leaving the villages and townships.
I wonder if the cement jungle made by man clouds the questions that nature provokes.
Just a thought.
