Answer:

THE TIME OF PHYSICAL FORMATION AND DEVELOPMENT OF EARTH IS CALLED Hadean eon TIME

Explanation:

A solid crust formed as the Earth cooled through time, and liquid water could exist on the surface. The Hadean eon, which started with the planet's creation and ended 4.0 billion years ago, is the period before a trustworthy (fossil) record of life.

The Hadean, pronounced HAY-dee-n, hay-DEE-n, is the epoch of Earth's history before the Archean. According to the International Commission on Stratigraphy (ICS), it started with the Earth's creation around 4.6 billion years ago and concluded 4 billion years ago. The ICS still refers to its status as "informal" as of 2016.  American geologist Preston Cloud first used the word to describe the time before the first known rocks on Earth. He named it after the Greek underworld Hades. W. Brian Harland later created the almost exact phrase, the Priscoan Period, from the Latin word priscus, which means "ancient." The eon is referred to as the Pre-Archean in other earlier writings.
