لَوۡ كَانَ فِیهِمَاۤ ءَالِهَةٌ إِلَّا ٱللَّهُ لَفَسَدَتَاۚ
The only convincing argument is that if Quran, multiple Gods means chaos.,because God is perfect and 2 perfect beings can not agree onto something that’ll require perfection in different aspects at the same time. Perfect harmony and true justice can only happen if there’s only 1 Godwith all the perfect/absolute attributes. Other arguments r quite weak I think Nature doesn’t tell us there’s 1 God. Look at the multiple gods in every prehistoric society. Mountains of data from archeological findings to suggest multiple gods were imagined and worshiped. Not a single society had worshiped 1 god without partners so clearly nature is not monotheistic How does universal harmony explains 1 God? Multiple humans have invented cars, rockets, space stations. All worked in perfect harmony! So multiple creators can create a harmonious being. And how do we know universe is harmonious anyway? What about hurricanes, tsunamis, landslides, wild fires etc ?? There r sacred texts where God has spoken, Vedas r an excellent example. Upanishads, Puranas all speak about God and other gods Yes, 1 God is from no one but either he creates other gods or part of Him transforms into another god and so on
