No one can be aware that Hebrew is an African language - because it is not an African language.
The favored term now for the language family which includes Hebrew and the other Semitic languages is "Afro-Asiatic." Some of the languages are indigenous to western Asia, others to northern and eastern Africa. There are five branches to the Afro-Asiatic language family: Semitic, Berber, Cushitic, Egyptian, and Chadic. Egyptian survives only in the form of Coptic (used in the Coptic Church the way Latin used to be used in the Catholic Church, but no longer used in daily life as a first language).
I don't know if there is any way to determine if the proto-language from which the later languages descend was spoken in Asia or Africa. The late Martin Bernal thought they started in Africa because there is a greater diversity of them on that continent.
As to Hebrew, after it developed as a language, being African, that would apply only to the time when the Children of Israel lived in Egypt.
