Asked in Earth Sciences
What eon are we in now?
5th Edit: The ancient Greeks referred to an eon as being an eternity, so by that definition, we would be in the one and only eon, but in geology, an eon amounts to about 1 billion years, making the Earth be 4.6 eons old, so, the answer would either be the first eon, or the 5th eon. Depends on how you look at it.

How long did the Precambrain last?
Precambrian is an informal term for the time before the Cambrian Period, the first period of the Phanerozoic Eon. The Precambrian consists of three eons, the Hadean, the Archean, and the Proterozoic. The Hadean Eon is about 760,000,000 years long. The Archean Eon is about 1,300,000,000 years long. The Proterozoic Eon is about 1,960,000,000 years long This comes to a total of 4,025,000,000 years.
Asked in Time
In science how long is an eon?
An eon is a made up of two or more eras. They are defined in terms of what was happening on the planet in biological and geological terms rather than in number of years. We are now 541 million yeras (Myr) into the current eon - the Phanerozoic eon. Before that was the Proterozoic eon which lasted 1959 Myr, the Archean eon (1500 Myr) and the oldest, the Hadean eon (500 Myr).
