I erased my mac through disk utility and i restarted my mac and there was no Startup disk and so i went to recovery mode and i see that recoverey mode booted in Macos Mountain Lion

Sometimes Internet Recovery Mode will only boot into the OS which originally shipped with the Mac from the factory (it is annoying). If this happens, then just install Mountain Lion, then make sure Mountain Lion is fully patched & up to date so that you can download a macOS installer for a more recent version of macOS which is compatible with your Mac. You can find links to various macOS installers within this Apple article which also includes optional instructions to create a bootable macOS USB installer):

You can check which versions of macOS are compatible with various Apple hardware by using this article:

FYI, after erasing the drive the first time, you should have quit Disk Utility, then selected the "Reinstall macOS" option instead of rebooting.
Hi,
Try booting with Command Option R and erasing again; this is supposed to allow installing the newest OS available for your Mac.
