If Christianity ever arrived in Somalia it would definitely had come from neighbouring axum rather then far distant places like Yemen or RomeWe traded with Sabaeans, Persians and Indians far more than Axumites. We received cultural influence and products from them, mostly. Nothing wrong with that. What did we get from Axumites? Injere (Canjeero)? That is nothing.
Studies have shown we got religious influence from Himyarites and Romans who we used to trade with. We had Jewish population in the north, don't forget that.
Look at sophisticates quote
Apparently some sites at awbarkhadle
Had Ethiopian orthodox crosses rather then Himyarite or romantic style crosses
I remember reading about this in Sada Mire's (2016) paper.
