If you bought this device used then your Apple ID never downloaded El Capitan.
If you haven't erased your hard drive, reboot normally, go to the App Store, and download El Capitan using your Apple ID. You can try to download it at the link below. If it won't let you, then your only options are to upgrade to Sierra/High Sierra/Mojave or find an older computer where you can download it using your Apple ID.
