Earth is a pretty unique planet in our solar system since it is the only one with a large amount of water and also a relatively large moon. Now researchers claim that water came to earth due to formation of the moon.

Earlier studies tell us that 4.5 billion Years Ago when the solar system was formed, the ‘dry’ material (which formed the Earth) was separated from the ‘wet’ material, the later being rich in water (which were the meteorites).

Now scientists used the Molybdenum isotope to distinguish between dry and wet materials and found that the entire water on Earth came from the collision of the protoplanet Theia who’s collision on Earth 4.4 billion years ago formed the Moon. So, there would be no water if there would be no Moon.
