'Firebase Init' says it created a file, but no file exists

I'm trying to use firebase to collect email addresses for an email list which I'm going to export, but every time I try to initialize, it says it created the file (or folder if i leave it as public), but I can't find anything of where it created.

You're about to initialize a Firebase project in this directory:

  /

Before we get started, keep in mind:

  * You are initializing your home directory as a Firebase project
  * You are initializing in an existing Firebase project directory

? Which Firebase CLI features do you want to setup for this folder? Press Space 
to select features, then Enter to confirm your choices. Hosting: Configure and d
eploy Firebase Hosting sites

=== Project Setup

First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add, 
but for now we'll just set up a default project.

i  .firebaserc already has a default project, skipping

=== Hosting Setup

Your public directory is the folder (relative to your project directory) that
will contain Hosting assets to be uploaded with firebase deploy. If you
have a build process for your assets, use your build's output directory.

? What do you want to use as your public directory? caf
? Configure as a single-page app (rewrite all urls to /index.html)? Yes
✔  Wrote caf/index.html

i  Writing configuration info to firebase.json...
i  Writing project information to .firebaserc...

✔  Firebase initialization complete!

the index file doesn't exist, and I can't deploy either.

The project is new, it doesn't let me select the project, but I'm assuming that's because I only have one project??
