Consider the following Quranic verses:
"Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation) before we clove them asunder? and we made from water every living thing. Will they not then believe?"
( Quran 21:30)
Only after advances have been made in science, do we know that cytoplasm, the basic substance of the cell is made of 80% water. Modern research has also revealed that most organisms consist of 50% to 90% water and that every living entity requires water for its existence.
Was it passible 14 centuries ago for any human being to guess that every living being was made of water? Moreover would such a guess be conceivable by a human being in the deserts of Arabia where there has always been scarcity of water? The following verse refers to the creation of animal from water:
"And Allah has created every animal from water." ( Quran 24-45)
The following verse refers to the creation of human beings from water:
" It is He who has created man from water: then has He established relationships of lineage and marriage: for thy Lord has power (over all things)." (Quran 25-54)
