new iphone X keeps asking for old apple id password

After I set up my new iphone X, i kept getting asked for the password for an old apple id in addition to the current one. I skpped over this part and eventually got the phone set up. Then I noticed that many of the songs in my music library won't download. It says its becuase the songs were purchased with the old id. Now many of my apps won't load either becuase of the same reason. The problem is that old id has been unused for over 10 years. I don't remember the password and can't reset it because the Email server no longer exists. I tried to reset the password using security questions but I couldn't answer the question. (It was, "name of your two daughters?" I have boys, no girls.) How do I get the phone to forget the old apple id?
