Macbook reboot gone extremely wrong

I wanted to clean EVERYTHING on my Mac to make it a bit faster, but in recovery mode I accidentally erased all the group of Macintosh HD, instead of just the Macintosh HD disk. Later my laptop "rebooted", meaning it went black and then it started again, only to read a few seconds later on the page that I was following the process that I had to reinstall again Monterrey in that same page.

When I went to try and reinstall it, a globe appeared, when in reality I was trying to get to the same page as before using CMD + R, It said "Internet recovery" and I kept it going to see if it was able to recover anything, but it ended up on a screen with an Error "-1008F".

Everything I tried (CMD+R, CMD + OPT + CTRL + R, OPT + power button, CRTL + OPT + R + P, etc.) leads to the folder with the question mark or the failed internet recovery.

Can I do anything to make my Macbook start again? I don't have a time machine backup –as I wanted to erase everything– and my Mac does not recognize an external hard drive (I connected it to the usb-c port on the top-right of my Mac).

If it helps, my Mac is a MacBook Pro of 2018 and 8GB of RAM running (or at least it was :'(...) with the latest version of OS Monterrey.

Thank you so much <3
