Welcome to the internet. I guess that you'll also find a lot of requests for /phpmyadmin/*, /wordpress/* and a bunch of other software that you didn't install. There's background chatter on the internet, constantly scanning for known vulnerabilities (or just creating an index of installed software for the time when there is a vulnerability).
Moreover, you don't state the originating IP address that's requesting this document but ask who's doing it. You should check your access log. If it's within your own network: Check the originator. If it's from elsewhere on the internet: Disregard. It's 404 anyway - the correct answer. Just like you'll find requests for /robots.txt and /favicon.ico, even if you never reference them anywhere.
