i just copped myself a macbook 2013 11"inch
I do not understand what that means but any Mac from that era was built do recognize Mac OS Extended disk formats, so if it has been upgraded to a more recent macOS version it will not recognize newer disk formats.
I do understand the Mac is in Recovery mode, but Disk Utility shows no disk on which to install macOS. The solution is to boot macOS Recovery and use Disk Utility to completely erase the device.
Follow these instructions: Erase and reformat a storage device in Disk Utility on Mac - Apple Support.
Pay attention to Steps 3 and 4: Be sure to choose View > Show All Devices. The "Device" in its context refers to the entire storage device, meaning not a volume or partition subordinate to that device. For the file system format (Step 6) select Mac OS Extended (Journaled).
Then, you can quit Disk Utility, which returns to the main Utilities screen. Proceed to reinstall macOS.
