it was formed during the creation of our solar system and simply dust, comets, ice and other debris left over.
accretion
It's called accretion.
Nebula
Our solar system began forming within a concentration of interstellar dust and hydrogen gas called a molecular cloud. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center called solar nebula

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.
Earth did not exist 5 billion years ago. What would become Earth was part of a collapsing cloud of gas and dust that would eventually form the solar system. Earth itself formed about 4.55 billion years ago. When it first formed it was made largely of molten rock.
Nebula
This is referred to as the debris cloud.
According to the astrophysicists that I believe and follow, our solar system began to form about 4.6 billion years ago.
