About 2900ybp a group of T-L208 crossed the Gulf of Aden and settled in modern day Djibouti and Somaliland. What i want is to know is why did they do so and which Semitic language did they speak?

[Podlachian]

Does ot mean that Arabs are from Africa?

T-L208 was already found in Moroccan Neolithic (about 3000 BCE).
