Making WordPress site the home page

I am not really sure how to describe my problem. All of my website’s pages have mydomainname.org/nameofthepage as the permalink address. Therefore, if I type domainname.org into the browser, it does not go to the page I would like to be the “entry” page of the site (which is now named domainname.org/home). When I try to edit the permalink of this page by deleting everything after domainname.org, it reverts back to domainname.org/home. What am I doing wrong? Thanks!
