There could be some truth to it. There’s a connection between predynastic Egypt and Mesopotamia. According to ancient Egyptian mythology, the first dynasty of Egypt was established by the Falcon tribe of Horus who are believed to be of Mesopotamian origin. The Gebel el-Arak knife, dating back 5450 years i.e predynastic Egypt, shows a Mesopotamian king controlling two lions possibly representing upper and lower Egypt and on the backside of the handle there’s an image of a battlefield.
Somalis and Beja have a genetic connection, not just haplogroups, but on whole genome analysis and one study indicates that the Somali-Beja split happened around 3400 years ago for the Somali-Hadendoa (Beja) and 3700 for Somali-Beni Amer (Beja/Tigre).
This confirms the proposed theory that the ancestor of Somalis, the proto Somalis, migrated from what is today south Egypt/North Sudan through Eritrea, where they stayed for some time, before making another migration along the Red Sea coast into the Somali Peninsula.
A side note, a study done by Steele et al. have also demonstrated that northern Somalis have a slightly higher percentage of Eurasian DNA than south Somalis and Abyssinian groups without any recent influx of foreign DNA. This could be the result of genetic isolation and if that’s the case then the northern Somalis are the modern representatives of the proto Somalis.
However it could also come from South Cushites who possibly inhabited the Somali Peninsula before the proto Somalis.The people depicted on Las Geel are most likely South Cushites and they were 60-65% West Eurasian.
i agree with your assessment, to add to that as well the new kingdom of Egypt 18th,19th and 20th dynasty rulers/pharaohs had a mother tongue which was not Ancient Egyptians but close to it. the new kingdom came from the south and kicked out the Hyksos rulers of Egypt who were from syria and the last ruler was the 17th dynasty. I visited some sites near aswan and luxor with someone who was a bisharin Beja who are officially the only recognised decedents of the new kingdom egypt by the state of egypt. he took me to old closed temples and he was reading the holographic to me and told me what they were saying on the wall, i was shocked and not surprised in the same time.
those temples has been closed for more than 30 years for "renovation" but the truth is the Egyptian government do not want the world to see as many westerners can read it these days and notice what it says. basically what it said on the wall is all the new kingdom pharaohs attribute their origin to the southern land "Ta seti" which was East sudan+Eritrea+djbouti+northern part of somalia. He told me their native tongue was a language which is what he believes to be the proto type language which beja+afar split from.
The guy literraly showed me word by word and translated it wall after wall and everything pointing to the south, he told me Ancient Egyptians was a secondary language to them and the main language was a language from the land of Ta seti. Now Ta seti split later to the northern part "Medjay" East sudan + northern Eritrea, and the southern Part "Punt" which is rest of Eritrea + djbouti and northern somali. Medjay=Beja and Punt=Afar/saho. i remember he read an inscription once which said that in military meetings they all spoke with that "southern language" to make sure the hyksos who some remained in egypt and lived among the population could not spy on them as the danger from"syria" was always not finished with.
Those Bisharin Beja are amazing wallahi any somali in here who might visit egypt in the future go to towns like Luxor and aswan. forget about the noba people just look for Bisharin Beja and tell them you are somali and watch how they would see you as a family member who have not seen you in years. their features you sense like horner living in south egypt.
In regards to south cushites in the somali peninsula maybe they mixed with the incoming cushites waves coming at a later dates or maybe groups like the omotic tribes have link with them who lives in southern/western Ethiopia.
