Creation of life from water.
Everyone knows that water is essential for all life forms to survive, and that phrases like "50-90% of the weight of living things consists of water" appear regularly in encyclopedias. Furthermore, 80% of the cytoplasm (basic cell material) of a standard animal cell is described as water in biology textbooks. It is essential in the chemistry of all biological systems. Water provides the medium in which the transport of molecules can occur in reactions.
Animals in dry regions, therefore, have been created with mechanisms to protect their metabolisms from water loss and to ensure maximum benefit from water use.
Regarding plant development, the famous 17th century scientist, Jan Baptista van Helmont discovered in 1640s that water in soil is the most important element.
As water is necessary for all life, scientists look for the evidence of water in their search for life, whether it is somewhere on Earth, or even somewhere else in our solar system or beyond.
The analysis of cytoplasm and its appearance in textbooks took place hundreds of years after the revelation of the Qur'an. It is therefore impossible for this fact, now accepted by the scientific community, to have been known at the time the Qur'an was revealed. Yet, attention was drawn to it in the Qur'an 1,400 years before its discovery.
Allah created every [living] creature from water. Some of them go on their bellies, some of them on two legs, and some on four. Allah creates whatever He wills. Allah has power over all things. (Qur'an, 24:45)
Have not those who disbelieved known that the heavens and the earth were one connected entity, then We cloved it asunder and that We made from water every living thing? So will they not believe? (Qur'an, 21:30)
And it is He Who created human beings from water and then gave them relations by blood and marriage. Your Lord is All-Powerful. (Qur'an, 25:54)
