It is not backward. The keywords to a program are like skeletons to a body and highways to a city. While we agree that the organs or even muscles are more meaningful to a body's function and the business inside buildings off the road are the essence of a city, skeletons and roads provide structures and makes it possible for those "meanings" to render. Without it, one can't practically dive into the more complex and meaningful stuff without getting lost. While the keywords are not the real meaningful part of code, it contributes the most to organize and to manage the complexity of code. So functionally, in terms of managing code and making writing and reading sophisticated programs possible, keywords are the most important parts.
