To even suggests cushtic people migrated into Ethiopia from Sudan is laughable.
1- First and foremost, cushtic people have been living in Ethiopia and specifically northern Ethiopia since before the advent of civilization in the area. Ethiopia is the home of the Afroasiatic languages as it contains the most numerous and most branchs of the language family.
2-Meroe was actually destroyed during the 2-3rd century by The Great Ezana, Christianity along with Aksumite tradition spread west from northern Ethiopia into Sudan. You can even find ancient Aksumite churches, with Ethiopian style of art, and even Ge'ez writing.

Egyptian language, instead belongs to the
Afro-Asiaticfamily. She bases this on its sound inventory and

5-It is evident that Sudan has always been a nilo-Saharan inhabited region, even the kush empire was not cushtic.
