Chapter 3: The Man in the moon and the Face on Mars

In chapter 3 Carl Sagan shows that the human body is responsible for most of the popular culture myths like the face on mars.

The face of Virgin Mary on a tortilla.

A cloud of Abraham Lincoln.

He says that these are all products of the central nervous system that is primed from infancy to recognize patterns, specifically those that are faces, especially the mothers face. If we look at 100,000 pictures, it's not surprising that occasionally we'll come upon something like a face. With our brains programmed for this from infancy it would be amazing if we couldn't find one here and there. We humans have a talent for deceiving ourselves. Skepticism must be a component of the explorer's toolkit, or we will lose our way.
