We have been blessed by God with vast oceans covering our planet, but from where did all this water come from?

Recently the Infrared Space Observatory which reveals the chemistry of the galaxy has shown that water is formed near stars as they come to their end. This occurs when primordial hydrogen combines with oxygen formed by the stars themselves. This water is in the form of frost or ice adhering to the dust cloud of the dying star.

Some of this water was caught up in the formation of the solar system and in the beginning, served to cool stellar matter thus making cloud compression by gravity easier. Other water may have been added by comments striking the earth during its early history. The biblical description is meaningful even today as we read,

"The earth was a formless wasteland
while a mighty wind swept over the waters."
(Gn 1:2)

Along with water the chemistry of life may also have begun in interstellar space. Astronomers have discovered that meteorites, comets and interstellar dust contain the chemical bases of life such as amino acids. I suppose that this basic chemistry for life was present in the interstellar dust which was caught up in the formation of our solar system, although some of this chemistry may have been brought to earth also by other cosmic encounters.

Then God said:
"Let the waters teem with an abundance
of living creatures ...." (Gn 1:20)

We know that life exists in extreme conditions of deep sea thermal vents as described by Peter Tyson: "If there is a harsher place to live than a hydrothermal vent, it hasn't been found yet. Pitch darkness, poison gas, heavy metals, extreme acidity, enormous pressure, water at turns frigid and searing -- this sea floor environment seems more like something from deep space than from our own deep sea." (webpage: Nova Into the Abyss Living at Extremes) Once our earth with its oceans began to form, "some scientists suspect that life began in the midocean ridges where hot magma emerge from matter." 75 For billions of years life evolved countless forms in the oceans and when eventually it moved to dry land rain water provided for the life of plants and animals.

Reptiles which adapted to live in deserts developed bodies which are water tight. They reproduce internally and their eggs are also water tight except for peruses which allow the embryo to breathe.Their excretion is not in the form of urine but a white semimoist paste or powde, all of this to conserve water in their bodies.

Water is essential for life. Water is constantly sculpturing the surface of our planet: it's a universal solvent in the biosphere where it is essential for biochemical reactions. Living cells are made of aquatic solutions, suspensions and emulsions with water present from 70% by weight in many living animals and 98% in jellyfish like forms. Likewise, plants are 50% to 75% water and water takes part in the decomposition of living forms. Without water our planet would look like the Moon or Mars. (Webpage: Water for human beings)
