Appears you may have erased too much from the Mac's drive; so now
you would need to start up, from an online re-installer. And that needs
the internet to get, load, and start the Mac from that installer.. to begin.
Note there are 'macOS Utilities' available from the online macOS startup;
w/ instructions on 'how to erase' a drive, suggest means toward that end.
The options that should work if instructions could be diligently applied,
would be among choices; in this Support article, and its associated links.

You may or should use the link within this article and elect to Erase the
drive; that could involve reformat drive. Most, usually to HFS+ Journaled.
So, you might need to erase your disk first. ~Blue text is instructions link.
(Then again, later Mac hardware determines the format; APFS or HFS+)
Read though entire article and be aware the choices may require depth
to understand cause-&-effect repercussions involved; as these take time.
Hours; maybe even overnight, etc; or could even need replacement drive.
Always best to make, keep, and maintain good backups; to include the
automatic Time Machine on external USB drive. And learn how to make
and use boot-capable full system clones, on capable external drives.
Good luck & happy computing!🐌|🐢
