I'll answer the original Q directly from the Quran
مَا اتَّخَذَ اللَّهُ مِن وَلَدٍ وَمَا كَانَ مَعَهُ مِنْ إِلَهٍ إِذًا لَّذَهَبَ كُلُّ إِلَهٍ بِمَا خَلَقَ وَلَعَلَا بَعْضُهُمْ عَلَى بَعْضٍ سُبْحَانَ اللَّهِ عَمَّا يَصِفُونَ {91}
[Pickthal 23:91] Allah hath not chosen any son, nor is there any god along with Him; else would each god have assuredly championed that which he created, and some of them would assuredly have overcome others. Glorified be Allah above all that they allege.
Indeed.. each God should come champion what he has created and may the most powerful of them win? A ship of this magnitude can't be steered by more than one captain.. and that is really all there is to it!
