Identify and discuss the elements and situations in Daniel Defoe's Robinson Crusoe that make it a novel from the perspective of verisimilitude

The simpler form of the question is: What makes Defoe's story, Robinson Crusoe seem plausible. In other words, what makes this story seem as if it could have really happened?

One of the ways this is done is to go into great detail about the topography of the area, analyzing and creating a realistic environment. Specific dates, times, and existing places are used to bolster the belief. Additionally, there is the entire day to day life that Crusoe lives; from building his hut, to the way he procures food.
