Ussher chronology. The Ussher chronology is a 17th-century chronology of the history of the world formulated from a literal reading of the Old Testament by James Ussher, the Archbishop of Armagh and Primate of All Ireland. The chronology is sometimes associated with young Earth creationism, which holds that the universe was created only a few ...
The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. [2]: 145 The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, [34] [35] [36] soon after the formation of the Earth's crust and the Earth
These timelines of world history detail recorded events since the creation of writing roughly 5000 years ago to the present day. For events from c. 3200 BC – c. 500 see: Timeline of ancient history. For events from c. 500 – c. 1499, see: Timeline of post-classical history. For events from c. 1500, see: Timelines of modern history.
Creation of the Earth. Wenceslaus Hollar (1607–1677) Dating creation is the attempt to provide an estimate of the age of Earth or the age of the universe as understood through the creation myths of various religious traditions. Various traditional beliefs hold that the Earth, or the entire universe, was brought into being in a grand creation ...
Nation-building is a long evolutionary process, and in most cases the date of a country's "formation" cannot be objectively determined; e.g., the fact that England and France were sovereign kingdoms on equal footing in the medieval period does not prejudice the fact that England is not now a sovereign state (having passed sovereignty to Great ...
c. 4,300 Ma – Nectarian Era begins on Earth. c. 4,250 Ma – Earliest evidence for life, based on unusually high amounts of light isotopes of carbon, a common sign of life, found in Earth's oldest mineral deposits located in the Jack Hills of Western Australia. [4] c. 4,100 Ma – Early Imbrian Era begins on Earth.
Early Earth. Early Earth is loosely defined as encompassing Earth in its first one billion years, or gigayear (Ga, 10 9 y), [1] from its initial formation in the young Solar System at about 4.55 Ga to some time in the Archean eon in approximately 3.5 Ga. [2] On the geologic time scale, this comprises all of the Hadean eon, starting with the ...
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
