Try Command-Option-R for Recovery, and get the latest macOS version supported.

Any Mac that can run macOS 10.12 can run macOS 10.13, or later.

Use macOS Recovery on an Intel-based Mac - Apple Support

If you have another Mad, try downloading 10.13 there, and build a bootable installer.

It’s also possible that something that caused you to erase and re-install is also causing problems for Recovery.

To add to @MrHoffman's excellent suggestion......if the latest version of macOS compatible with your Mac is macOS 10.13 High Sierra, then you may encounter a new error message related to the server being unavailable. In that case, follow the instructions for Fix #3 in the following article:
