For long as human beings have observed and reflected on the natural world that they inhabit, they have told stories about the formation  of Earth. Creation narratives occur in just  about  every system of belief. They may involve the scions of primeval deities, abstract powers, or-in our modern scientific worldview- physical objects and the forces that govern their interactions.


There is also a human urge to want to date the beginning of the world as we know it. In the early 17th century, after carefully studying biblical chronologies that gies  that recounted span of many kingships long lists of family descendants, Anglican Archbishop James Ussher announced as a fact that the creation of the Earth had occurred at 9 a.m. on October 23 in the year 4004 B.C. Ussher's calculations and their implications were widely accepted for more than a century, but then scientific study of rock formations and fossils suggested that  had existed longer than Ussher sosed. We now know that Earth and the rest of our solar system formed    
together about 4.6 billion years ago from a huge cloud of gas and dust fol- lowing a gigantic star explosion within the universe. The sun formed at the center of some debris. Chunks of matter coalesced into planets, including Earth. In a process known as accretion, Earth's gravity continued (and continues) to attract debris, which becomes incorporated into its surface. Over time the fledgling Earth took shape. Repeated impacts, radiation from the sun, and internal  processes caused planet to settle into layers: an inner core,an outer core ,a mantle, and a crust. A few fragments of the original crust remain. interior melting traveled to the surface, creating volcanic processes that spewed forth lava and gases. These gases, including water vapor, m gave rise to Earth's primitive atmosphere. The resulting precipitation accumulated over time to form Earth's d first oceans. These materials and processes also set the stage for the appearance of life on planet Earth some 3.5 billion years ago.
