A theological parable - Does Mr. Ford exist?

Take a Ford motor car. It is conceivable that someone from a remote part of the world, who was seeing one for the first time and who knew nothing about modern engineering, might imagine that there is a god (Mr. Ford) inside the engine, making it go. He might further imagine that when the engine ran sweetly it was because Mr. Ford inside the engine liked him, and when it refused to go it was because Mr. Ford did not like him. Of course, if he were subsequently to study engineering and take the engine to pieces, he would discover that there is no Mr. Ford inside it. Neither would it take much intelligence for him to see that he did not need to introduce Mr. Ford as an explanation for its working. His grasp of the impersonal principles of internal combustion would be altogether enough to explain how the engine works. So far, so good. But if he then decided that his understanding of the principles of how the engine works made it impossible to believe in the existence of a Mr. Ford who designed the engine in the first place—in philosophical terminology he would be committing a category mistake. Had there never been a Mr. Ford to design the mechanisms, none would exist for him to understand.

What does this tell us about the so-called rational arguments of some atheists who think faith is the same as blind faith?
