 The Evolution of Life
The Earth's age of final formation as a planet is estimated at around 4600 million years.
This used to be called the "Hadean Period" from 4600 - 3800 million years ago, but has recently (in 2004) been renamed Eoarchean.
During this period the heavier molten iron sank to the middle of the newly forming Earth, to become the core.
