Where did water on earth come from?

Question

It had to first come from something, or maybe in the beginning of time it was like any other the rock, the exception being that ice melts at a comfortable level that life could form. Other rocks can melt, but at a higher rate, so its almost like rock/lava/water.
Does anyone really know?

I know WHAT water is, but I want to know from WHERE and HOW water came to earth.

IDEAQUEST: Do you even understand what that means? Because I don't and I'm sure the people that wrote it meant it that way.

Answer 1

Most of the water came from the elements of Hydrogen and Oxygen coming together at the right temperature and pressure.
Some of the water came from comets hitting the earth 4.6 billion years ago. There were lots of comets back then, and earth was probably hit daily with them for 1000's of years.

Answer 2

Genesis Account:

1:6 And God said: 'Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.'

1:7. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so.

1:8 And God called the firmament Heaven. And there was evening and there was morning, a second day.

1:9 And God said: 'Let the waters under the heaven be gathered together unto one place, and let the dry land appear.' And it was so.

1:10 And God called the dry land Earth, and the gathering together of the waters called He Seas; and God saw that it was good.

Answer 3

According to some it was an accident where hydrogen and oxygen accidently collided and made water eons ago.

But where did hydrogen and oxygen come from?

The Genesis account sounds much more plausible to me.

Answer 4

there is no shortage of water in the outer solar system, although it's all present as ice. earth was probably quite dry when it formed, and acquired its water later, from comets.

Answer 5

2 molocuels of hydrogen and one molocuel of oxygen=H2O
