“And We sent down water from the heaven in proper quantity, and we made Earth is dwelling, and We are Able to take it away.”
Water on Earth came from outer space, particularly from ice in comets and meteors. When those comets enter our atmosphere the heat generated on entry vaporizes this ice into the atmosphere.
The Christian Bible says that God created water directly on Earth, however, the Quran says that God sent down water from outer space and then made Earth its dwelling:
And We sent down water from the heaven in proper quantity, and we made Earth is dwelling, and We are Able to take it away.
If God made Earth its dwelling (فَأَسْكَنَّاهُ فِي الْأَرْضِ ) then this means that water formed in outer space. In another verse, the Quran explains how water came down from outer space. The clouds are enslaved between the Earth and the heavens but the water itself came from the heavens above the clouds:
In the water which Allah sent down from the Heavens and brought with it life to Earth after being dead and gave life in it to every kind of land animal; And in directing the winds; And in the clouds that are enslaved between the Heavens and the Earth; [All these] are Signs for a people who comprehend.
So the water itself came from the heavens above the clouds. Here God is not talking about rain (matar or wadk in Arabic) instead God is talking about water (مَاءٍ).
In another verse, the Quran says that water originally came from the heavens (above the clouds) in the form of ice. There are mountains in the heaven that have ice inside them; those mountains could fall on Earth making a very bright flash:
Can’t you see that Allah makes the clouds move gently, then joins them together, then makes them into a pile? Then you see rain come out from within? And He sends down from heaven mountains with ice inside them; that strike whomever He wishes or miss whoever He wishes; Its flash almost blinds you.
God sent down from the heavens (above the clouds) mountains with ice inside them! The clouds are enslaved between the Heavens and the Earth but the water itself originally came from the Heavens (above the clouds) in the form of ice in mountains. They make a flash, this is the description of comets and meteors when they hit our atmosphere.
Rain hits everyone (no exceptions) however the Quran referred to mountains: “that strike whomever He wishes or miss whoever He wishes”. Of course, the meteor that killed the dinosaurs was the size of a mountain. If we get hit with a meteor the size of a mountain we too will die. It is Gods’ choice that we live or die.
How could an illiterate man who lived 1400 years ago have known that water originally came from ice in comets?
More than half your body weight is water. Animals and plants on Earth are mostly water. All life in our universe also needs water. When scientists search for life on exoplanets they only look for planets with water; no water means no life. Ho,wever Muslims knew about this 1400 years before it was discovered.
Do not those who disbelieve see that the heavens and the Earth were meshed together then We ripped them apart? And then We made of water everything living? Would they still not believe?
In the Quran, all life, on Earth and in the heaven, depends on water.
How could an illiterate man who lived 1400 years ago have known that all life in the universe also needs water?
Water covers about 71% of the Earth’s surface. This is also the same ratio as the word “Sea” and the word “Land” appear in the Quran. “Sea” appears 32 times and “Land” 13 times. The ratio of “Sea” to the total (Sea + Land) = 32/(32+13) = 71%.
