This is a substance that covers almost 90% of the earth's surface, a substance that's makes up the 60% of our body and a substance that's colourless, tasteless or odorless.

Yes, you got us right we are talking about the basic necessity of each and every living organism's life. The Water, although we take this magical fluid for granted. The presence of water in the entire solar system is impossible, so how did the earth have a lot of it.

This is Now You Know and in today's video we will tell you that where all the water on earth did actually came from?

Water is a precious fluid; it acts as a base for all living organisms. Water is made up of 2 molecules the hydrogen and the oxygen. While hydrogen was present in our atmosphere from the beginning oxygen came in much later.

These were present in our dusty solar system and that collided with our planet after its formation. Many research states that water on earth was brought by ice bearing comets and the asteroids that bombed the earth millions of years ago.

Apart from that many say that the water was present on the earth from is beginning as the rocks contains H2O molecules in them.

So, until now no one specifically know that where did it actually came from. Was it from the dusty atmosphere or the asteroids or the combination of both the possiblities.

What were the condition may be the water we see and drink today reached us through a massive and chaotic journey.

So, where do you think the water came from?
