IMO, this flat earth stuff was put out there to discredit conspiracy theorists.
Stop dreaming, to have an haplogroup contained in "black people", doesn´t make you "black".
It only shows from where your ancestors may have originated, the egyptians lived in Africa, so proving they originated from east Africa is nothing new or surprising, that doesn't make them part of a sub-saharian tribe or "race".
The ancient egyptians were very different from their nubians neighbors, they represented them with clearly differencies in skin color and physionomy.
Also they treated them as foreigners and barbarians, so no matter how much you wish it in your dreams, the egyptians weren't "black".
Stop dreaming that people who weren't black africans were like that only because it makes you feel better.
