Before the Earth, the solar system was a swirling disk of gas and dust. This material eventually clumped together to form the planets, including Earth. Scientists believe that the Earth began to form about 4.5 billion years ago.
Earth formed about 4.5 billion years ago from a cloud of gas and dust called the solar nebula. Gravity caused the nebula to collapse, forming the Sun at the center and the remaining material to clump together to form planets like Earth.
The Earth has no rings. There may be a VERY tenuous dust cloud, but that mass would mostly have been skimmed off by the Moon's gravity, causing it to either fall to Earth or ejecting it from near-Earth space. So if there is a dust cloud near the Earth, it is too thin to detect.
The solar system formed from a rotating cloud of gas and dust called the solar nebula about 4.6 billion years ago. Gravity caused this cloud to collapse and form the sun at its center, with the remaining material forming the planets, moons, asteroids, and other objects in the solar system.
It's called accretion.

accretion
The solar system formed from the gravitational collapse of a cloud of interstellar gas.

The gravitational force pulled together swirling dust and gas in the early solar system, causing it to condense and form the Earth. This process is known as accretion.
A spinning cloud of dust began to compress to form the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets.
They form themselves.
