The oldest written scripts ever discovered is the Proto Saharan, found by the Kharga oasis in what was known as Nubia in present day Sudan, so called by archaeologists. It dates from about 5000BC.
The Nsibidi Writing system of west Africa also dates back to 5000 BC.

The Nsibidi (Nsibiri) Writing system used among the Igbo, Efik, Ibibio, Annang, Banyang, Efut, Oron in Nigeria and Cameroons Originated among the Ejagham (Ekoi) people of Cross River, Nigeria, While the Greek Writing was not fully use until 1400BC and Asian languages until 3000BC

The Nsibidi and other written African languages are known to have developed outside Arab or European influences.

African languages are several centuries older than Asian written forms. According to Dr. Clyde Winters book The Ancient Black Civilizations of Asia, the oldest known form of writing developed between 5000 and 3000 B.C in sub-Saharan Africa Now known as Proto-Saharan writing.
