Yeah, Jesus was jewish (jews were darker skinned back then) and christianity as a religion began upon Jesus’s death in the middle east. Paul and Sylas traveled through Syria. John-Mark and Bartholomew traveled and spread the word around Persia. I don’t understand what your point is here.
Okay this is extremely pedantic but technically speaking areas which are now Arabic like Lebanon and Syria were not yet Arabized at the time. There were some Arab groups in the region like the Nabateans in modern day Jordan, but the transmission of Christianity to the Roman Empire was primarily via Jews and then Greek and Roman converts
