A new study found that water reached the earth during the moon's formation more than 4 billion years ago, in a phenomenon that probably occurred when an "old planet" was called "Thea" on Earth.

Planetary scientists from the University of Munster in Germany have gathered evidence that the Thia, the size of Mars, collided with our planet and ignited life on Earth.

It is said that the collision led to the transfer of large amounts of water between the "Thea" and the Earth, "to form the oceans we know today.

The theory suggests that the earth was formed as a dry planet in the inner solar system and that there was no water on the surface.

Earlier, many scientists believed that water entered the Earth through meteorites, from the outer solar system, called "carbon" meteorites.

Previous studies have shown that during the solar system about 4.5 billion years ago, "dry" materials were separated from "wet" substances with dry objects in the inner solar system, so the theory of "carbon" meteorites seems logical.

However, German scientists used a substance called molybdenum isotopes to distinguish between carbon and non-carbon materials on Earth, to create a & # 39; genetic footprint & # 39; for the planet and to determine whether the source of matter exists in the inner or outer solar system.

Using this method, they discovered that wet carbon materials reached the earth from the outer solar system. They claim that the only collision that can explain the amount of carbon on the planet is the Thia effect, which is said to have contributed to the formation of the moon.

"Our approach is unique because it allows us, for the first time, to connect the origin of water to the earth by forming the moon," concluded Thorstein Klein, a professor of planetary science at the University of Munster. "Without the moon there could be no life on earth."

The findings were published in the current issue of Nature Astronomy.
