It depends how you look at it. From a historical perspective, water is older than the sun. Water was created before the sun existed as part of the Big Bang 13. 8 billion years ago. Hints of the water molecules were discovered in space as early as 10 billion years ago, shortly before the sun was formed approximately 4.
5 billion years ago through the gravitational collapse of a huge cloud of gas and dust.
From a scientific perspective, however, no one can claim an exact age for either the sun or the water. The sun and the Earth (including its water) have experienced repeated cycles of heating and cooling over time, so exact dating of either object is difficult to ascertain.

Who is the oldest planet?
The oldest planet in our solar system is believed to be Jupiter, according to evidence from meteorites, various objects in the asteroid belt and other cosmic bodies. Scientists were able to determine the approximate age of Jupiter by studying the composition of its elements and its history of formation.
It is estimated that Jupiter is at least 4. 5 billion years old, which is roughly half the age of the universe. Additionally, Jupiter has the most mass and gravity compared with other planets in our solar system.
This means that its gravity pulls more space debris and other kinds of material toward it, thereby helping to build up its gaseous layers and forming the base for the creation of planets in our solar system.
In short, evidence suggests that Jupiter is the oldest planet in our solar system, as well as the most massive by far.
What existed before the Sun?
Before the formation of the Sun, the Solar System was composed of two classes of cosmic bodies: planetesimals and gas and dust clouds, which were mostly hydrogen and helium gases. A huge interstellar cloud, the Solar Nebula, is thought to have caused the formation of the Sun and the other elements of the Solar System.
This massive cloud of gas and dust was likely created from the debris produced by several supernovae explosions in the earlier stages of the Milky Way’s formation. The gas and dust particles within the Solar Nebula became increasingly dense over time, due to the cumulative effect of gravity pulling them together, until it finally triggered the gravitational collapse that formed the Sun.
This collapse also caused the debris to spin, giving rise to the orderly structure of the Solar System we know today.
What is the oldest thing on Earth?
The oldest thing on Earth is thought to be a zircon mineral grain discovered in Western Australia. The grain is estimated to be around 4. 4 billion years old, which makes it the oldest known material on Earth.
Zircon is a mineral composed of zirconium silicate and is commonly found in sand and gravel deposits. It is incredibly resistant to erosion and natural weathering, leading to its extreme durability and longevity.
Scientists believe that these ancient grains can be used to gain insight into the conditions of Earth’s earliest history. According to the Australian National University, these minerals are “time capsules” that are able to provide a glimpse into the early history of our planet.
Scientists are still trying to uncover how much information zircon grains can provide about the origins and age of the Earth.
Is our sun the oldest star?
No, our sun is not the oldest star in the universe. Although it is approximately 4. 6 billion years old, studies suggest that the universe itself is 13. 8 billion years old, meaning that there are other stars in the universe which are older than our sun.
In addition, the existence of some stars suggests that they were created from the remnants of other, older stars which have gone through the process of stellar evolution and gone on to become different and more evolved stars.
Therefore, while our sun is considerably old, other stars have likely been formed during the formation of the universe and could be much older than our sun.
How old is the water?
The age of water depends on where it’s located and its source. On a global level, the majority of the earth’s surface is covered by water, and much of it has been around for millions of years. For example, the oceans contain some of the oldest water on earth and are estimated to be around 4 billion years old.
However, most of the water that appears in rivers, lakes and groundwater systems is much newer, dating back only a few thousand years. Groundwater, which is found deep in the earth’s crust, can be up to 250 million years old.
There are even some pockets of ‘fossil water’ that are believed to have been untouched by the atmosphere for up to 2 million years. Ultimately, the exact age of a given body of water depends on its source, but scientists believe that it is constantly being renewed and recycled.
Was the Earth all water before?
No, the Earth was not all water before. The Earth formed around 4. 5 billion years ago, and the first few hundred million years of its history were quite different than what it’s like today. While there was certainly water on the Earth, it wasn’t until much later that the oceans we know today began to form and cover a significant portion of the planet’s surface.
During the first few centuries, the Earth’s surface would have been incredibly hot and became gradually cooler. Volcanic eruptions are thought to have released gases which contributed to the formation of a primitive atmosphere.
This atmosphere, combined with a lot of water, helped to form some of the oceans of the modern age.
The Earth didn’t start to look much like it does today until around 500 million years ago, where the majority of Earth’s modern life started to emerge from the seas. With the development of tectonic plates, the combination of land and sea that we know today was created about 200 million years ago.
So, while there was water on the Earth since its formation, it wasn’t until later that the oceans began to form and dominate the planet’s surface. It took around 3. 5 billion years for the Earth to develop into the planet we know today.
When was water created?
Water is an essential part of life, and its origin is believed to date back to the dawn of time. Scientists believe that much of the primordial water on Earth has been in circulation since the formation of the planet, more than 4.
5 billion years ago. During its first 500 million years, Earth’s water was primarily locked in its geological formations. The water found in Earth’s oceans, lakes, and rivers today was created around 3.
8 billion years ago, resulting from planetary cooling that caused the water vapour in the early atmosphere to condense and form bodies of liquid water. This Early Water is believed to have come from comets and asteroids.
Heavy water, which includes a heavier isotope of hydrogen, is thought to have arrived from interstellar clouds that have interacted with stars. The water cycle including evaporation, clouds and rain, and the movements of Earth’s continental plates also help shape the Earth’s water supply.
Recent studies indicate that variable amounts of water may also exist beneath the Earth’s surface.
When did water first appear on Earth?
The exact moment when water first appeared on Earth is the subject of ongoing scientific debate. The earliest archeological evidence for water on Earth dates back 4. 3 billion years, to shortly after the planet’s formation.
This suggests that water was part of the planet from the start. One hypothesis suggests that comets impacting the young Earth could have brought substantial amounts of water to the planet. However, key isotopic evidence suggests that water on Earth predates the impact of comets, calling this into question.
Other evidence has suggested that water may have come from within Earth, forming pockets of it in the early days of the planet’s formation. This could explain why crystals dissolving in water have been found in rocks that are over 4 billion years old, suggesting that Earth’s oceans were already in existence at that time.
This leads to the suggestion that Earth was born ‘wet,’ with water coming from within the planet, generated by the planet’s formation and heating processes, as well as from outside sources such as comets and meteorites.
While it is impossible to pinpoint precisely when water first appeared on Earth, it is clear that it has been part of the planet from its earliest days.
What was on Earth before water?
Before water, Earth was a barren landscape with little oxygen in the atmosphere. The surface of the planet was likely composed of a mix of elements that were common throughout the solar system, such as carbon, nitrogen, oxygen, and other elements like sulfur, phosphorus and chlorine.
The presence of oxygen in the atmosphere was limited, and concentrations of hydrogen and other light elements, such as neon and helium, were low.
The early Earth likely formed through repeated impacts of bodies – primarily asteroids and comets – which released a variety of gases and solid material that coalesced and formed the Earth. Temperatures on the young planet may have been as high as 5000 K (4727 degrees Celsius).
This intense heat likely vaporized any water that may have been present on and around the Earth, along with other volatile substances.
After the heavy bombardment period, the Earth’s surface began to cool off and by 4. 4 billion years ago, global temperatures had dropped significantly. It is believed that liquid oceans formed about 4 billion years ago, when cometary impacts delivered significant amounts of ices and volatiles, leading to increased temperatures and significant amounts of water.
So, liquid water and the oceans became a feature of the planet about 3. 8 billion years ago.
Why was there no water on early Earth?
In the early stages of Earth’s formation, water was not present on the surface. This is due to several reasons. Firstly, when Earth was first forming, it was made up of metallic and silicate rocks that are not conducive to liquid water.
Secondly, conditions on Earth were too hot due to the heavy bombardment of meteorites during the first 700 million years of Earth’s history. This would have vaporized any liquid water present on the surface.
It is likely that Earth’s water was formed later as a result of the outgassing of lighter elements from the Earth’s mantle, caused by the cooling of Earth’s core. The outgassed elements likely formed small droplets of water in the primordial atmosphere which condensed and rained down on the Earth’s surface.
It is possible that the water in the Earth’s liquid oceans was sourced from the comets and asteroids that bombarded the early Earth.
Finally, recent studies have suggested that the Earth’s water may have been contained in a “primordial soup” form on smaller asteroids and other asteroids. These pieces of matter could have been incorporated into Earth when it first formed and allowed enough liquid water to exist on the planet’s surface.
In summary, the lack of water on early Earth was the result of a number of factors, including the composition of the planet’s original material, the intense meteorite bombardment, and later the outgassing of lighter elements from the Earth’s mantle.
While the exact origin of Earth’s water remains up for debate, this is the current understanding of why Earth was without water in its early stages.
