A Correct answer
Explanation

The Big Bang theory describes the origin of the Universe approximately 13.8 billion years ago when all matter and energy expanded rapidly from an extremely dense and hot state. It was not an explosion in space, but rather an expansion OF space itself. The theory does not relate to Earth's formation specifically.
