WHERE DID EARTH'S WATER COME FROM

We are often referred to as the "water planet." But where did this water come from? Here is an interesting article from Science Daily that talks about where this natural resources originated. Meteorite study suggests Earth may have been wet since it formed. A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed -- instead of far-reaching comets or asteroids delivering such water. The findings suggest that Earth may have always been wet.
Enstatite chondrite meteorites, once considered 'dry,' contain enough water to fill the oceans -- and then some.
