what is the longest and oldest era of earths history?
The Longest Era of Earths History is Paleoproterozoic Eralasting 900 million years.The largest unit of time in relation to Earth's history is the super-eon. Super-eons are divided into eons. Eons in turn are divided into eras, eras are divided into periods, periods into Epochs and Epochs in Ages.Precambrian Super-Eon (4,600 - 542 Ma)Hadean Eon (4,600 - 3,800 Ma)Archean Eon (3,800 - 2,500 Ma)Eoarchean Era (3,800 - 3,600 Ma)Paleoarchean Era (3,600 - 3,200 Ma)Mesoarchean Era (3,200 - 2,800 Ma)Neoarchean Era (2,800 - 2,500 Ma)Proterozoic Eon (2,500 - 542 Ma)Paleoproterozoic Era (2,500 - 1,600 Ma)Mesoproterozoic Era (1,600 - 1,000 Ma)Neoproterozoic Era (1,000 - 542 Ma)Modern Super-Eon (542 Ma - Now)Phanerozoic Eon (542 Ma - now)Paleozoic Era (542 -251 Ma)Mezozoic Era (251 - 65 Ma)Cenozoic Era (65 Ma - Now)

In general speech, an eon can refer to a very long period of time. In science, an eon is the largest division in the geologic time scale.

We are currently in the Phanerozoic Eon.
