What are the two periods of history?
The time in history can be divided into two main periods- Prehistoric period and Historic period..
What is our era?
Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age. … The Greenlandian, the oldest age of the Holocene (also known as the “lower Holocene”), began 11,700 years ago, as the Earth left the last ice age.
What is the largest Eon?
An eon, the largest division of the geologic time scale, spans hundreds to thousands of millions of years. Geologists generally agree that there are two major eons: the Precambrian eon and the Phanerozoic eon.
What are the 12 periods of the Phanerozoic eon?

What is God’s age?
I guess not earlier than 200,000 years ago. I’d even say there was no God before the end of the Neolithic age, and that means God is roughly 7,000 years old.
What are the 5 eras?
The book divides the timeline of the universe into five eras: the primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the universe.

What was before Stone Age?
The Prehistoric Period—or when there was human life before records documented human activity—roughly dates from 2.5 million years ago to 1,200 B.C. It is generally categorized in three archaeological periods: the Stone Age, Bronze Age and Iron Age.
What are the four ways to understand the Earth’s age?
Generally speaking, scientists have developed four different methods of determining the age of the earth….How Do Scientists Measure Earth Age?Radiation Measurement.Stratigraphic Superposition.The Fossil Record.
What era do we live in 2020?
Holocene eraThe present year, 2020, can be transformed into a Holocene year by adding the digit “1” before it, making it 12,020 HE. Years BC/BCE are converted by subtracting the BC/BCE year number from 10,001. Beginning of the Meghalayan age, the current and latest of the three stages in the Holocene era.
