Pronunciation: [he͡ɪdˈi͡ən ˈiːɒn] (IPA) 
The Hadean eon is a geological period that spans from the origin of the Earth, about 4.6 billion years ago, to the formation of the first solid rocks, about 4 billion years ago. It is characterized by intense volcanic activity, frequent impacts from asteroids, and high temperatures that made the planet's surface inhospitable for life. Some synonyms for the Hadean eon include the Priscoan era, the Azoic era, and the Eoarchean era, which all convey the concept of an ancient and barren Earth before the emergence of life. Other terms such as the chaotic era or the fiery era also capture the violent and turbulent nature of this period.
