Life in the universe is water based.
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 no life. However Moslems knew about this 1400 years before it was discovered.
[Quran 21.30] 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 Earth's surface. This is also the same ratio the word "Sea" and word "Land" appear in the Quran. "Sea" 32 times and "Land" 13 times. The ratio of "Sea" to the total (Sea + Land) = 32/(32+13) = 71%.
