وَجَعَلْنَا مِنَ الْمَاءِ كُلَّ شَيْءٍ حَي
And We have made from water every living thing.
(Even though this has been stated in the Qur’aan, regardless) however, there are Biologists who say that some of the Bacteria does not live upon water.
Some of what?
(That some) types of germs or bacteria do not live upon water.
In regards to the meaning of the verse, it does not mean live upon water. Its origin. The origin of its existence is from water and this is the meaning of the verse. Not that it [the creation] lives upon water.
