wp-load.php

I noticed something in firebug that kept popping up, mydomain.com/wp-load.php. I also noticed that this is loading jquery ver 1.7.1. Is this something that I can/should get rid of. I have plugins on my site running jquery 3.3.1. So far, it doesn’t appear to break anything, but the fact that it’s there seems like it could create some kind of problem so I figured I’d check with the experts.
