Suddenly Everything "Earth's early history was violent and dramatic. Its mass began to take shape slightly over 4.5 billion years ago. Within 50 million years, its core had formed and in turn, generated a magnetic field. However, it was not until the atmosphere and surface of the crust were relatively stable, about 3.8 billion years ago, that life had a good chance to evolve and thrive" (p. 16). Palmer, Douglas.
