Beginners don't trust the command line

After learning Git in the summer, I went to my some of my friends and classmates who study CS and told them: "I'm going to force you to learn Git". I don't want to work alone!

One thing kept happening over and over: whenever I explained how branches work and how we switch branches, and I showed them how files do change in the working directory (using ls command -- in either WSL or git bash), they nodded and thought it made sense. Then I open the file explorer (finder) and show them that the files DO change; they go quiet for a second, "wow" they say. It's as if the command line isn't something concrete.
