The most accepted theory to explain the emergence of water from the practical and scientifically point of view can be summarized that the earth at the beginning was throwing lava from the inside, these lava were dashing in the atmosphere so that it was releasing millions of tons of the heated water vapor that ascend in the air till it touch the higher layers of the atmosphere to condense to make the heavy rains.
Hence, the water in earth was emerged from the underground of the earth which means that God be He exalted and blessed take out its water from the inside of it, God says :
( And after that He spread the earth *and brought forth there from its water and its pasture*and the mountains He has fixed firmly* (To be) a provision and benefit for you and your cattle.)
(Sûrat An-Nazi' at- verse 30-33).
Look at the sequence of the cosmic events, at the beginning the earth was a flammable celestial body which was separated from the sun and then it started to turn around it, the turning of earth , separation from the sun and then the earth was spread till it got its spherical shape are what the Qur'an told us in His saying:
( And after that He spread the earth),
in this verse a sign for the sphericity of earth as the word spread came from the roundness of the egg. During the cooling operation the water vapor started to ascend from the lava and that what the Qur'an told us in His saying :
( and brought forth there from its water and its pasture).
So the water got out from the earth to start the formation of life and to bring the different plants. At that time the mountains hadn’t been formed yet as it took thousands of millions of years to form the mountains!
When the earth started to become cold, the earth crust started to be formed and that crust started to move because it stands on the lava (thousands of degree of heat)!as a result of these movement the different parts of the crust started to collision with each others to form the mountains. Mountains have roots which extends to thousand of meters inside earth crust as it work as a balance for the earth to fix it during its turning like the anchor for the boat, so God says:
(and the mountains He has fixed firmly* (To be) a provision and benefit for you and your cattle.)
(Sûrat An-Nazi'at- verse 30-33).
The scientists say that the water was descended from the sky to be lodged inside the earth which formed seas and rivers, therefore God talks about the descending of the water from the sky and also from inside the earth. Scientists say that both facts are right
Now the Question is: what may happen if the salt of the seas is able to evaporate like the water of the seas? God be He exalted put the law of gravity to enable life to continue. As the salt is heavier than the water so it can't ascend in the air ….but the water can, because the density of water vapor is less than the density of the air. Scientists calls it the "Archimedes' principle".
This law which is related to the density of the materials guarantees the evaporation of water and to keeping the salt in the seas to ensure the descending of the pure water from the sky, God says :
(Then tell me about the water that you drink * Is it you who cause it from the rain-clouds to come down, or are We the Causer of it to come down?*If We willed, We verily could make it salt (and undrinkable): why then do you not give thanks (to Allah)?)
(Sûrat Al-Wâqi‘ah- verse 68-70).
Therefore, the scientific miracle in the Qur'an is not only limited to mentioning the scientific facts but it includes the actual sequence of these facts. There is no contradiction between the modern science and the words of Allah. This is evidence that the creator of the universe is the one who descended the Qur'an.
