Earth is the third planet from the sun in our solar system.  It was created 4.6 billion years ago when a large star possibly passed by a nebula, and the nebula was spun and created a disk.  At the center of the disk, the Sun was formed and the eight planets of our solar system followed quickly afterward.  Earth is currently the only planet known to support life.  The entire history of Earth can be found on the page Geologic Time Scale.
