Quran 21:30 – Creation Of Living Things From Water
Every generic or specific statement needs to be understood in its context. The verse is drawing attention to the observable phenomena of the world. In this context God says, that every living thing which you see is created from water. Also, this is not a scientific statement to add knowledge but based on the knowledge of the audience which they already have, and the purpose is to make basis for the conclusion of oneness of God and resurrection that this meticulous creation should meet some meaningful culmination etc.
