According to scientist, how is earth believed to have formed

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen thats what they believe

The Earth started forming about five billion years ago. The Earth is formed from space gas, dust, and other galactic materials. Like the other planets in the Solar System, the Earth was created when material that orbited the early Sun began to accumulate into a spherical body.
