When you first learn programming, you don't know what a class is, or a method, let alone a static method.

But if you teach people using Java, you have to teach them to write this:

    public class Main {
      public static void main(String[] args) {
        System.out.println("Hello world");
      }
    }

...instead of just:

    print "Hello world"

The latter is easy for a student to understand. With the former, you just have to tell them to use it without understanding it, and that they'll understand it later.
