Where did the water first come from.?

Answer 1

It the solar nebula from which our solar system formed there was an abundance of Oxygen and Hydrogen atoms. Oxygen is itself very unstable, and readily bonds with two hydrogen atoms in order to become stable - this creates the compound that we call water. So... There was a lot of water in the early solar system. That is quite simply where the water came from...

How did the water get to earth? Well, a lot of it has always been here -- it was attracted to earth because of its gravitational pull, and since the water is much less dense than the rock that makes up most of the planet, the water migrated to the surface of the planet. Water was also probably transported to earth by icy comets which were much more common in the early solar system - but this probably didn't contribute all that much to the total amount of water on earth.

Answer 2

The cosmologists and earth scientists believe it was comets and vulcanic activity. Water is simply two atoms of hydrogen, which is abundant in the universe, and one atom of oxygen.

Answer 3

Noah’s Flood - Where did the water come from?

In telling us about the world-changing Flood in the days of Noah, the Bible gives us much information about where the waters came from and where they went. The sources of the water are given in Genesis 7:11 as “the fountains of the great deep” and the “windows of heaven.”
