A 2015 video uploaded in science YouTube channel, Curious Minds, which claims Earth water dates back to Mesozoic era, has been trending again five years after. As humans have only existed on Earth for about 200,000 years, this means we are consuming most of dinosaurs' pee or urine, as the video claims.

Scientists claim water in Earth contains almost 100% dinosaurs' urine

The video explains that about 121,000 cubic miles of water go around the Earth every year through precipitation. During the Mesozoic era, dinosaurs reigned for around 186 million years, giving them much "time to drink a lot of water."

The video also noted that while most water molecules in an eight-ounce glass were never been consumed by another person, "almost every single molecule has been drunk by a dinosaur." Like humans, dinosaurs also released all water that they drunk, then they drink anew. This means humans who have only existed for 200,000 years ago are consuming most of these giant creatures' urine.

Around 121,000 cubic miles of water, which is equivalent to 42 Superior Lakes, is received on Earth every year. This much water flows through the sea, lakes, and rivers as well as kept under the ground or taken in by people and animals.

Steve Maxwell and Scott Yates wrote in their book "The Future of Water: A Startling Look Ahead" claims that we consume the same water, which dinosaurs drank in the past. "Fossil fuels get burned and are gone forever. Water remains," the authors wrote as reported by the Daily Mail.

Meanwhile, in the book entitled "The Big Thirst," Charles Fishman claimed that water molecules are so resilient and could be about millions of years old. Fishman added that each glass of water we drink include a lot of water that "has already passed through a dinosaur and come out the other end."

How was Earth water formed?

Water covers more than 70% of the planet Earth and it constantly cycles from rivers and oceans to the clouds before it precipitates back again. It surrounds us and even makes up around 60% of human bodies. However, with all its existence, where does water came from?

In a TED-ed video entitled "Where did Earth's water come from?," Zachary Metz discussed how water is formed. Primarily, a water molecule consists of two part, hydrogen and oxygen. Scientists believe that immense pressure at the Earth's core pushed hydrogen atoms to combine and form helium. After stars exploded into supernovas, new elements spread across the universe and combined into compounds such as H2O.

However, a bigger question to ask is when did water arrive on Earth? One theory is that Earth rocks already included minuscule amounts of water when they were formed. Then, high temperatures caused it to evaporate back into space.

After hundreds of millions of years, the atmosphere was later formed after molten rock inside the core of the Earth discharged volcanic gasses and created a layer that trapped escaping water. Meanwhile, scientists also believed that much water was brought back to the Earth through ice-bearing comets or by asteroids that blasted the planet for millions of years.

However recent studies challenged this theory as carbonaceous chondrite meteorites, which formed right after the solar system was formed, scientists discovered that these rocks contained water as well as mineral chemical composition that is the same as Earth rocks and those from an asteroid, which was of the same age as the Earth. This suggests that a substantial amount of water was already accumulated even without an atmosphere.

How does water move around the Earth?

Science says that 3,800 million years since the first evidence of water was found, water has never left the Earth. This means the water that existed when dinosaurs first showed up 230 million years ago is the same liquid we are consuming today. Yes, we are using the same water used in the Jurassic World.

Despite the locations of all water on Earth, everything has been used and reused since the beginning of time. Water has continuously gone through the water cycle, switching its form from liquid to solid or gas, then moving through other elements of nature where water is cleaned before it changes locations.

The water reuse is described by International Water Association Board Member Daniel Nolasco as "dinosaur pee." Unfortunately, unlike dinosaurs, humans use water in ways that hurt the Earth's environment. Humans pull water out of the ground, then pump it through domestic and agricultural areas, most of the time being treated with chemicals and contaminated with human wastes.

Water has been essential for humans, dinosaurs, and other creatures. Thus, it is vital to start protecting the water resource for the years to come. ­­­­­
