In this episode, Ben and Caleb talk through the Cain and Abel story, and what might the author be trying to communicate through this sad story.  They set up a major theme that will be traced throughout the whole Bible:  when Humans trust God and obey Him, they are reflecting his image-- they are acting the most human.  When they give into sin, it is like an animal crouching ready to devour us-- we in fact become more animal like rather than human.
