The big bang did not make the Earth. The big bang took place 13,700,000,000 years ago. That is 13.7 Billion years ago.

The earth formed long, long after the big bang... the earth formed about 9,000,000,000 years AFTER the big bang... that is the earth formed about 4.5 billion years ago....

Basically the earth formed when the sun formed. Stars like the sun form from the gas and dust in the Milky Way galaxy. Gravity causes the gas and dust to collapse and form denser objects like stars and planets.
