It has been suggest that Earths water came from meteorites, now there is some samples from the moon that might suggested that in ancient times that meteorites had brought water to the MOON.

"Water deep inside Earth and the moon may originate from the same source: ancient meteorites, scientists say.
The findings hint that water may have existed on Earth before the giant impact the planet received that created the moon, and that the moon possessed water from its earliest moments, scientists added. It remains a mystery exactly how water found within the moon survived this violent collision, though.
Water is vital to life as we know it, with organisms found virtually everywhere there is water on Earth. When Earth was born, the ingredients of the planet's water most likely would have formed beyond the orbit of Earth. As such, all the water on the planet must have come from either comets or meteorites hurtling inward from the outer solar system.
Until recently, scientists thought the interior of the moon was bone-dry, originating as the moon did from the molten debris of a giant impact of a Mars-size protoplanet against Earth about 4.5 billion years ago. The heat of this collision should have baked all the ingredients of water out of the moon. However, five years ago, the first evidence of hydrogen was discovered in lunar samples from the Apollo missions. Hydrogen is a main ingredient of water, along with oxygen"......
