Paleozoic eon
Phanerozoic is the eon which geologic time scale means visable life.
The Archean Eon is the period in which the first life on Earth appeared.
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.
There are two: EON which is the first, and then the second EONA.
The one in enterna forest. Its not hard to find!

The largest divisions of the geologic time scale are: Hadean Eon (4.6 to 3.8 billion years ago) Archaen Eon (3.8 to 2.5 billion years ago; this is when the first bacteria existed) Proterozoic Eon (3.8 billion to 542 million years ago) Phanerozoic Eon (542 million years ago through today; this is when the first complex multicellular life forms evolved.)
I'm not sure about Phanerozoicums but, the PhanerozoicEonis the current eon in the geological timescale, and the one during which abundant animal life has existed. It covers roughly 542 million years and goes back to the time when diverse hard-shelled animals first appeared. Its name is derived from Greek and means make life appear, since it was once believed that life began in the Cambrian, the first period of this eon.
the eon that constitutes the earlier (or middle) part of the Precambrian, in which there was no life on earth. It precedes the Proterozoic eon. Also called azoic .
In fact it does! At lv. 30, I believe and it will be a stronger and better DonphanYes. It evolves into Donphan, a Ground-type pokemon, at Level 25.
