How did the Earth begin ?

Around 4.6 billion of years neither the Earth nor any of the planets existed .
There was just this vast , dark , very hot cloud of gas and dust swirling around the newly formed Sun .
Gradually ,the cloud cooled and the gas began to condense into billions of droplets .
Slowly these droplets were pulled together into chumps by there own gravity - and they carried clumping until all the planets , included Earth were formed .
But it took another half a billion years before the Earth had cooled enough to form a solid crust with an atmosphere around it .

Earth began life as hot gases and dust spiraling around the new born Sun .
