No one really discovered water. It has been on Earth as long Earth has been here. No living organism can live without water so technically you can't discover water.
Water is discovered by CAVENDISH
According to historians, the water cycle was discovered slowly over a period of painstaking years. However, Bernard Palissy is credited in the 16th century to be the scientist who compiled the theories that existed for years and "wrote" our modern hydrological cycle.
But much to the surprise of others, according to documents that date back to before the Common Era (thousands of years), knowledge of the water cycle existed then. These documents are found in the manuscripts of The Bible, and illustrating just one instance, found in the oldest manuscript known in the Bible, the book of Job:
Job 36:27-29
For He draws up drops of water,
Which distill as rain from the mist,
Which the clouds drop down
And pour abundantly on man.
Indeed, can anyone understand the spreading of clouds,
The thunder from His canopy?
Other examples are included as well. Thus, it would be difficult to answer when the cycle was first discovered.
Water has always been present on Earth, in one form or another. It was present, as ice and in water-bearing minerals called clays, in the planetesimals that the Earth was built from, and more water arrived in the form of comets. Some water, in the form of vapor and ice crystals, has always been present in the atmosphere of the Earth. Water vapor is also released from the Earth's interior by volcanoes.
But, I am being a little coy . . . I am guessing that you are wondering when Earth first had liquid water. The answer is probably earlier than you think! The Earth is about four and a half billion years old. It's difficult to study what the Earth was like back then, because the Earth's crust is constantly being recycled, and very few rocks are that old. However, we do have a little bit of rock that is 4,400,000,000 years old, found on the continent of Australia. This rock shows evidence that the surface of the Earth was solid and cool when this rock solidified, just 600,000,000 years after the Earth was formed!
There was even liquid water present where this rock solidified!
So as far back as we have geological evidence of what the Earth was like, there was liquid water present.
Water is a natural resource which means that is was here since the beginnings of the world.
The earliest water taps were invented by the ancient Egyptians and Greeks.
water is not created,it has already been on earth
Water first appeared on earth 4 B.y.a (billion years ago)
It has existed as long as water has existed.
