It didn't get IN there sometime or somehow, it just WAS there ALL the time, from the very beginning.
Sciences say that the sun was formed 4,600,000 years ago
No, water did not come from the asteroids a billion of years ago.
The Milky Way does not have a "father" in a literal sense. It is a vast spiral galaxy that formed billions of years ago through the gravitational collapse of gas and dust in space. It is home to billions of stars, including our own Sun.
The craters on Mercury, like those on other planetary bodies, formed over billions of years from impacts by asteroids and comets. The majority of Mercury's craters were likely formed during the early history of the solar system, roughly between 4.5 to 3.5 billion years ago.
Uranium on Earth was formed outside of our solar system, billions of years before Earth, mostly in our Milky Way galaxy.Uranium and the majority of the other heavy elements are formed by stellar nucleosynthesis in novas and supernovas.Heavy elements from the various sources in our galaxy combined with the mass of hydrogen that was the beginning of the formation our solar system around five billion years ago.Nucleosynthesis is the science that works to explain how elements are formed. Supernovae are responsible for the heaviest elements. Several other processes are involved in the creation of the lighter elements. See related links.
about 4.5 billions years ago.
The mantle is not the evidence of how earth looked like when it was first formed 4 billions years ago, but the biogenic graphites.
Sodium chloride is formed after the evaporation of water from sea and oceans, billions years ago.
The continents were formed after Pangea broke up, about billions of years ago, and the first signs of human civilization were 6,000 years ago.
Yours and mine. It was formed right here, a few billions of years ago
The elements in your body were once part of a star - billions and billions of years ago! Earth and everything on it was formed in space from bits and pieces of "star stuff."
The primary factor that was missing for billions of years that was necessary for protists to evolve was oxygen in the atmosphere. Billions of years ago, the atmosphere was mostly made up of carbon dioxide, carbon monoxide, hydrogen, nitrogen, and water vapor.

No one knows for sure. Although the first carbonic acid on earth formed naturally billions years ago.

Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
Billions of years ago.
