Nomadic african pastoralists in the neolithic arabian peninsula ?

Discalmer : this is mere speculation

Considering the evidence we now have for cattle domestication in the middle nile contemporary with that of the near east . But of a more nomadic pastoralism bent

What is the possibility that these guys spread nomadic pastoralism to the Arabian peninsula in the neolithic period.

The reason im entertaining this is because the earliest anicnet dna we have for the Arabian peninsula is from 300 b.c in eastern Arabia.

Considering this was the state of africa and the Arabian peninsula in 12000 b.c its very likely that whatever hunter gathers had existed in the arabian penisula and sudan/eygpt probably died out since were talking groups of several dozen to a few hundred people. So people obviously had to repouplate the areas after this as the climate improved over the next few millenia.

So basically I was thinking something along the lines of
1) proto-Cushitic hunter gathers coming out from their refuge in the horn of africa slowly and then reaching lower nubia
2) where they somehow domesticated cattle around 10 thosuand years ago for nomadic pasotralism and then expand from their in both directions.
