An old missionary student of China once remarked that Chinese history is “remote, monotonous, obscure, and-worst of all-there is too much of it.” China has the longest continuous history of any country in the world—3,500 years of written history. And even 3,500 years ago China’s civilization was old!

The start of any type of life form is, naturally, a topic of much debate. Some scientists estimate that ‘life’ began on our planet as early as four billion years ago. And the first living things were simple, single-celled, micro-organisms called prokaryotes (they lacked a cell membrane and a cell nucleus).

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

The evidence is overwhelming that all life on Earth has evolved from common ancestors in an unbroken chain since its origin. Offspring resemble their ancestors. Variant organisms will leave offspring like themselves. Therefore, organisms will diverge from their ancestors with time.

The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script, with the oldest coherent texts from about 2600 BC. Ancient history covers all continents inhabited by humans in the period 3000 BC – AD 500.

Originally Answered: What did they call years before BC? The references AD and BC are sometimes replaced by CE and BCE: Common Era and Before the Common Era. The Roman calendar was counted Ab urbe condita.in 753 BC; and it continued in use until the Anno Domini calendar was introduced in AD 525.

B.C. and A.D. Explained So 400 B.C. means 400 years before Jesus was born. A.D. comes from the Latin “anno Domini,” which means “in the year of the Lord.” A.D. applies to years following the birth of Jesus.

The letters “AD”, “BC”, “CE, or “BCE” are omitted. So 1 BC in historical notation is equivalent to 0 in astronomical notation, 2 BC is equivalent to −1, etc. Sometimes positive years are preceded by the + sign. This year numbering notation was introduced by the astronomer Jacques Cassini in 1740.

The rapid world population growth of the previous millennium, caused by the Neolithic Revolution, is believed to have slowed and become fairly stable. It has been estimated that there were around forty million people worldwide by 5000 BC, growing to 100 million by the Middle Bronze Age c.

Approximately 8,000 years ago

before Christ

Thus, the current year is written as 2021 in both notations (or, if further clarity is needed, as 2021 CE, or as AD 2021), and the year that Socrates died is represented as 399 BCE (the same year that is represented by 399 BC in the BC/AD notation).

we are living both in AD and CE. Christians use the word AD (anno domini) whereas non – Christians use the term CE (current era).

B.C. (or BC) – meaning “Before Christ”. Used for years before AD 1, counting backwards so the year n BC is n years before AD 1. Thus there is no year 0. C.E. (or CE) and B.C.E.

1006 BC—David becomes king of the ancient United Kingdom of Israel (traditional date). 1000 BC—The United Kingdom of Israel reaches its largest size, it is Israel’s golden age. c. 1000 BC—Nok culture in Nigeria.

The 10th century BC comprises the years from 1000 BC to 901 BC. This period followed the Late Bronze Age collapse in the Near East, and the century saw the Early Iron Age take hold there. The Greek Dark Ages which had come about in 1200 BC continued.

3000 BC – Sumerians start to work in various metals. c. 3000 BC – Knowledge of Ancient Near Eastern grains appears in Ancient China. 3000–2000 BC – Settled villages are widespread in Mesoamerica.

The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. Evidence of microbes was also preserved in the hard structures (“stromatolites”) they made, which date to 3.5 billion years ago.

Bacteria started living on earth 3.5 billion years ago. The solar system formed from dust clouds 4.5 billion years ago. The earth was initially too hot I think. Only after the earth cooled down, living organisms started living on earth.

The date of birth of Jesus is not stated in the gospels or in any historical reference, but most theologians assume a year of birth between 6 and 4 BC.

History based on written records appears quite late in human history. The first written records date back a little more than 5,000 years in Egypt and ancient Sumer. The earliest Sumerian records were made using reeds cut at an angle to make wedge-shaped (cuneiform) marks on clay, which was then baked hard.

In the Paleolithic period (roughly 2.5 million years ago to 10,000 B.C.), early humans lived in caves or simple huts or tepees and were hunters and gatherers. They used basic stone and bone tools, as well as crude stone axes, for hunting birds and wild animals.

England

English has developed over the course of more than 1,400 years. The earliest forms of English, a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century, are collectively called Old English.

English is the largest language in the world, if you count both native and non-native speakers. If you count only native speakers, Mandarin Chinese is the largest. Mandarin Chinese is the largest language in the world when counting only first language (native) speakers.

French

All in all, Mandarin is the best language to learn because of its growing economy and number of language speakers. Spanish and Arabic are next for the the top spots for the best language to learn abroad because of the sheer demand and job opportunities for them.

These countries include Belize, Botswana, Cameroon (co-official with French), Eswatini (Swaziland), Fiji, Ghana, India, Kenya, Kiribati, Lesotho, Liberia, Malaysia, Malta, the Marshall Islands, Mauritius, the Federated States of Micronesia, Namibia, Nigeria, Pakistan, Palau, Papua New Guinea, the Philippines, Rwanda.

The UK has the most local accents of any English speaker country. As such, a single “British accent” does not exist. However, someone could be said to have an English, Scottish, Welsh or Irish accent, although these all have many different sub-types.

Sociolinguist William Labov dubbed the New York accent the most recognizable accent in North American English. Not surprisingly, many of its attributes have entered the popular American lexicon. Learn how to speak with a New York accent.
