(1) No, it's not. The Aryans, or Indo-Europeans, started out as one entity. Then at one point in time, they split into western, mostly Iranian, branch, n an eastern, mainly Himalayan branch. The Himalayan Indians themselves would be the first ones to admit to an 'Aryan' origin, with or without British endorsement. In ancient times their place was called Arya Varta, the Land of the Nobles.
(2) No, it's not. It does not live or die on such a precept. But Knive, you just said it. Armenia, Anatolia n the Western Himalayas were all the playgrounds of the Cymmerians. While Northern Europe, if that turns out to be true, could have been the cradle, the so called Arya Vaeja (which suddenly got too cold) of Persian legend. The Cymmerians split into 2 branches somewhere in northeastern Iran, at some point in time, due to pressure from another dominant tribe, possibly the then up and coming Medeans.
One branch shifted northwest, to the Caucasus, from where they later spread further outwards, including to Armenia n Anatolia, as well as Southern and Eastern Europe, remaining initially as Cymmerians. This branch eventually clashed with the Assyrians in Anatolia n the Syrian-Mesopotamian regions. They later blended into their Iranian relatives, the Scythians, n later their former nemesis the Medeans.
The other branch moved southeast, to the Western Himalayas, where they later became known as the Kamboja, after some later Cymmerian king named Kambujiya. The Tajiks, Farsi speaking natives of Tajikistan, are said by some to be the modern day pure descendants of this Kamboja Cymmerians.
The Achaemenid Persian kings, beginning with Khouroush-e-Bozorg (Cyrus the Great), profess descent, through Hakhamanesh (Achaemenes), from this first King Kambujiya (Cambyses in Greek), whose name kept recurring among several post-Cyrus Achaemenid kings. By the time of Cyrus, however, the Cymmerians had blended into the Persians. Cyrus, in fact, was recorded as the half Medean, half Persian king who merged Medea with Persia.
Let me clarify, my Cymmerian can exist with or without the Aryan. It's up to the reader. The Persians would insist on the inclusive, I think. Anyway, all I'm saying, at this moment, is that, my Gomer/Kaiomerz/Gaiomard would still be founder of Cymmerian.
If an Aryan race existed, then Gomer/Kaiomerz/Gaiomard would also be the first Aryan. If not, he would be only the first Cymmerian.
