The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil, and ultimately descends from Proto-Indo European *erþō. From this it has cognates throughout the Germanic languages, including with Jörð, the name of the giantess of Norse myth.
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words 'eor(th)e' and 'ertha'.
This giant landmass known as a supercontinent was called Pangea. The word Pangaea means "All Lands", this describes the way all the continents were joined up together. Pangea existed 240 million years ago and about 200 millions years ago it began to break apart.
Earth is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic. There are, of course, many other names for our planet in other languages. Mars is the Roman god of War.
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. Jupiter, Saturn, Mars, Venus and Mercury were given their names thousands of years ago.
Sumerian astronomers named the sun, moon and five visible planets (Mercury, Venus, Mars, Jupiter and Saturn) after their great gods.
Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind".
With an environment devoid of oxygen and high in methane, for much of its history Earth would not have been a welcoming place for animals. 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.
10 And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.
Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere. If the Sun were as tall as a typical front door, Earth and Venus would each be about the size of a nickel.
Gaea, also called Ge, Greek personification of the Earth as a goddess.
It is called “Mother Earth” because during the Paleolithic they referred to a superior life-giving power and on the other hand also as an analogy to our mother, because without her we would not have life and much less a future, so we must protect her.
Earth was never formally 'discovered' because it was never an unrecognized entity by humans. However, its shared identity with other bodies as a "planet" is a historically recent discovery. The Earth's position in the Solar System was correctly described in the heliocentric model proposed by Aristarchus of Samos.
The Romans named the days of the week after the Sun and the Moon and five planets, which were also the names of their gods. The gods and planets were Mars, Mercury, Jupiter, Venus and Saturn.
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
The earliest time of the Earth is called the Hadean and refers to a period of time for which we have no rock record, and the Archean followed, which corresponds to the ages of the oldest known rocks on earth.
Miller and a few other scientists began to suspect that life began not in warmth but in ice—at temperatures that few living things can now survive. The very laws of chemistry may have favored ice, says Bada, now at the Scripps Institution of Oceanography in La Jolla, California.
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men's mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.
Anatomically modern humans emerged around 300,000 years ago in Africa, evolving from Homo heidelbergensis or a similar species and migrating out of Africa, gradually replacing or interbreeding with local populations of archaic humans. For most of history, humans were nomadic hunter-gatherers.
Vishnu, Lord of the universe, is a Hindu God known to have reincarnated into more than one form called Avatars. In other words, he is recognizable through the faces of other gods who receive praise within the Hindu beliefs. Here we have sculptures of Vishnu and a few of his forms ranging 8th-19th century.
While the planets are named after Roman deities in the Western world, they have different names in other contexts. The ancient Greeks called them by their Greek god names, unsurprisingly: Jupiter was Zeus, Mercury was Hermes, and Venus was Aphrodite.
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
