Kushites
of Kishites were an Afro-Asiatic
mountain people of Mesopotamia
from whom came Nimrod.
Their first king was Etanna who reigned immediately after the
end of Ice-Age deluges which submerged many costal communities.
They left their name in mountainous areas from the Caucasus
to as far as Afghanistan.
According to some scholars they eventually migrated around the
Oman & Yemen
coasts of Punt
to Ethiopia
in the 4th Millennium BC after being displaced by the Sumerian-speaking
Asshur-Shemites from the east.
