Earth's Formation

When the galaxy was new, a cloud of dust formed. The dust crashed into each other. This formed big rocks,they crashed into each other forming bigger rocks.They started heating up, melting. They formed a hot liquid called magma.By this time the earth a huge ball of rock and magma. Then, a slightly smaller rock crashed into earth(witch is still a ball of rock and lava.) This made a BUNCH of earth crust go flying into space. A thousand years later, the crust formed a big ball of rock, and crashed back into earth. Instead of harming earth, earth absorbed it, this formed the core. A couple million years later, the earth has cooled down, water is hear now (sorry I didn't explain how water got hear) and that is the earth's formation.
