This is the run down on the origins of each race. Arabic/Hispanic are direct descendants of Noah/Abraham from the blood line of Enki/Ea. Asians are direct descendants of Cain from the Bible who was also from Enki's blood line but had his genetic code altered for murdering Abel. The Negro/Sub Saharan South Africans are one of the few races not originally from earth, and were known as the Vegans/Hebrew who showed up about 75,000 years ago on earth during the days of Atlantis. There are two very different 'white' races on earth. The Aryans(blond haired blue eyed) are direct descendants of Marduk/Amun-Ra/Bel, former ruler of Egypt/Babylon who is Enki's first born son. The other white race are the Igigi/fake Jews who stole the Hebrews religion/identity to claim to be God's chosen people and are Khazars/Phoenicians/Ashkenazi and are technically white Asians who are descendants of an alien race who bred with Cain's people for the most part who invaded earth about 36,000 years ago during the days of Atlantis who created the Cromagnon species and are the source of RH- blood groups and are a reptilian speces. Native aboriginals are hybrids of what I believe that are a mix between the original Hebrew and Cain's. The reason you believe that the Negro have been on earth the longest is because the Annunaki themselves, or rather some of them were melanated as well, so many of the first races of earth possessed melanin but this did not make them one of the original Hebrew race. This is a basic run down and each race has a very unique history based on their interactions which has resulted in many hybrids created since the first humanoids were genetically engineered on earth which were the Neanderthal, about 480,000 years ago but the Annunaki which consists of two very different races were here for millions. Their people consist of two main races, the Orions(Ori) who are dark skinned/melanated and I believe are a feline species, and the Aldebarans(Lyran descendants) who are white and are likely a canine species.
