Difference between Earth and World
in the English language: The terms "earth" and "world" have distinct
meanings in the English language. "Earth" refers to the physical
planet we inhabit, while "world" can denote a broader range of
concepts, including other planets, human society, and even the universe. The
distinction is important as it affects how the terms are used in various
contexts, from geography to philosophy and literature. In this document, we have used the word ‘WORLD’ in a broader range of
concepts.

Ø Q. What is the Big Bang Theory?
A. A. The Big Bang Theory is the leading scientific explanation for the origin of the universe, proposing that it began as an extremely hot and dense point approximately 13.8 billion years ago and has been expanding ever since.

Prehistory[1]:
[1]Pre-history means literally “before
history”, from the Latin word for “before,” præ,
and Greek ιστορία.
[2] The Neolithic Revolution, also known as the Agricultural Revolution,
refers to the significant transition in human history from nomadic hunter-gatherer
societies to settled agricultural communities. This period marked the
development of farming, the domestication of animals, and the establishment of
permanent settlements, which allowed for larger populations and the rise of
early civilizations. It is considered a pivotal moment in human history,
occurring around 12,000 years ago.
[3] The
Solar System: The collection of eight planets and their moons in orbit
round the sun, together with smaller bodies in the form of asteroids,
meteoroids, and comets. The major
planets of the solar system are (in order of distance from the sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, which is very much known as ninth planet, is a
dwarf planet.

c. 6,000,000,000: The estimated age of the Solar System (variously estimated as 4,700,000,000 to 6,500,000,000)
c. 3,000,000,000: Moon parted from Earth. Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula.
c. 1,200,000,000: The lowest form of life appeared in the sea (algæ).
c. 570,000,000: Cambrian Age: trilobites and sponges in the sea.

Q. When does man first find out about dinosaurs?
A. No human being has ever met a dinosaur alive. Dinosaurs were animals that inhabited most parts of the world, but they died everywhere about 6,500,000 years ago. Dinosaurs were extinct when humans came into the world.
Dinosaurs are known to us because of their remains. These are bones, found in skeletons or separately; footprints in the rock; skin-prints, also in the rock; and eggs.
What’s the Difference Between Monkeys and Apes?
Monkeys and apes are both primates, which means they’re both parts of the human family tree. As distinguished relatives, we should probably be able to tell them apart. But when you look at a gibbon or a marmoset, how do you know which is a monkey and which is an ape?
The quickest way to tell the difference between a monkey and an ape is by the presence or absence of a tail. Almost all monkeys have tails; apes do not. Their bodies are different in other ways too: monkeys are generally smaller and narrow-chested, while apes are larger and have broad chests and shoulder joints that allow them to swing through trees (while some monkeys also have this ability, most of them are built for running across branches rather than swinging). Although you can’t recognize this difference on sight, apes have an appendix and monkeys do not. Apes are generally more intelligent than monkeys, and most species of apes exhibit some use of tools. While both monkeys and apes can use sounds and gestures to communicate, apes have demonstrated higher ability with language, and some individual apes have been trained to learn human sign languages.
However, perhaps the best way to remember, like with so many things, is rote memorization. There are only a handful of ape species, while there are hundreds of species of monkeys. If the primate you’re trying to place is not a human, gibbon, chimpanzee, bonobo, orangutan, or gorilla (or a lemur, loris, or tarsier), then it’s a monkey.
[1] Osteichthyes, popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes, which have skeletons primarily composed of cartilage. The vast majority of fish are members of Osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, over 435 families, and 28,000 species. It is the largest class of vertebrates in existence today. The group Osteichthyes is divided into ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 425 million years old, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes. Osteichthyes can be compared to Euteleostomi. In paleontology the terms are synonymous. In ichthyology, the difference is that Euteleostomi presents a cladistic view which includes the terrestrial tetrapods that evolved from lobe-finned fish. Until recently, the view of most ichthyologists has been that Osteichthyes were paraphyletic and included only fishes. However, since 2013 widely cited ichthyology papers have been published with phylogenetic trees that treat the Osteichthyes as a clade including tetrapods...wiki

500,000: The Peking Man Site, excavations in the early revealed evidence of human habitation from 500,000 to perhaps 680,000 years ago. The cave was excavated from 1927-37 yielding 200 human fossils (from 40 individuals) Homo erectus, more than 10,000 pieces of stoneware, several cinder layers indicating fire use in early man, as well as animal fossils from 200 separate species.
