The Big Bang Theory
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
The prevailing scientific theory is that the universe started with the Big Bang.
Scientists believe that galaxies were formed from the gravitational collapse of large clouds of gas and dust in the early universe. As these clouds collapsed, they formed smaller structures that eventually evolved into galaxies. The exact mechanisms of galaxy formation are still an area of active research in astrophysics.

They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
Scientists believe that the universe is primarily composed of dark matter and dark energy, which make up about 95% of its total content. The ordinary matter we are familiar with, such as gas and plasma, only accounts for about 5% of the universe's composition.

Scientist believe that the universe by a giant explosion called the big bang .
Far or near, all galaxies were thought to be formed in the first half billion years of the formation of the universe ... that is, about 13 billion years ago. Note that we're seeing the distant ones in a younger stage of development.
Scientists believe that the solar system formed about 4.5 billion years ago.
