The Early People
The Big Bang Theory is the name of the theory predicting how the universe and our earth was created. Scientists say that long ago a small dense ball of matter exploded sending out gases which made galaxies. Our galaxy, the Milky Way, was created 5 million years ago when forces of gravity pushed gases and dust together which made the sun and planets like our earth.
The first 600 million years of life was divided into 3 categories. Each category was divided into periods.
- Cambrian Period (600 million- 500 million years ago
- Ordovician Period (500 million- 440 million years ago)
-Silurian Period (440 million- 400 million years ago)
- Triassic Period ( 225 million- 180 million years ago)
- Jurassic Period ( 180 million- 135 million years ago)
- Cretaceous Period ( 135 million- 70 million years ago)
-Eocene Period ( 70 million- 40 million years ago)
-Oligocene Period ( 40 million- 25 million years ago)
-Miocene Period ( 25 million years ago)
-Pliocene Period (11 million- 1 million years ago)
-Pleistocene Period (1million-10 thousand years ago)
-Holocene Period (10 thousand - today)
The Big Bang Theory
Our earth was created 4.45 billion years ago by accretion from the
solar nebula.
Earth: The First Lifeless Years
5 billion years ago, Earth had no creatures, and was only a ball of gases, liquids, an solids, which was compressed creating oceans, land and many more. During this time, life was on its way to occurring. The sun's rays, lightning and gases from the earth's atmosphere fell into shallow oceans creating proteins, the main item a cell relies on and occur to live.
The First Life
2.5 billion years ago, scientists found the first life forms in Southern Africa. The forms of life were unicellular organisms known as bacteria.
During the Oligocene Period, 40-25 million years ago, early animals like the ape started to appeared.
The First Ape
During the the Miocene period, 25 million years ago, anthropoid ape started to appear in East Africa. They had elongated arms, no tail and a highly developed brain. The group includes gibbons, orang-utans, chimpanzees, and gorillas.
Anthropoid ape
There are six types of people that took part in creating today's civilization. The name of the six people are Australopithecus, Homo Habilis, Homo Erectus, Neanderthal Men, Cro-Magnon Men, and Homo sapiens sapiens.
1.2 to 4 million years ago, in Eastern and Southern Africa, lived a human-like creature named Australopithecus. This creature was apelike and walked on two legs but didn't walk like we do today. They had long arms and short legs, and had a brain the size of an orange. Due to their small brains, they did not know how to make advanced tools but used simple objects such as a twig or a rock. These creatures lived in trees. They did not do a lot of hunting since their main source of food were roots, nuts, fruit, and insects. But the Australopithecus did not have any art and clothing until they developed more.
Early People
Homo Habilis
Homo Erectus
Homo sapien Neanderthal's one of the early peoples who took part into creating today's civilization. These people lived apparently 10 thousand to 100 thousand years ago in a valley in Germany. The Neanderthals walked straight up, and their average height was 2 meters tall. They made simple clothing from animal hides to make coats. They lived in caves and used many tools made out of chipped rock such as knifes, spears, and borers. These people ate bears who invaded their shelters. Unfortunately, the Neanderthals didn't have any art this time.
Homo Sapiens: Neanderthal
Homo Erectus known as the "upright man" existed from 1.6 million to 300 thousand years ago, in Africa, Europe, Java, an island in Indonesia, and Peking, China. These early people lived in caves . They appeared as almost no chin, had bony eyebrow ridges, and their average height was 15 meters tall. Due to undeveloped vocal tract, they spoke very slowly. They used various but simple tools such as bones of animals and rocks to chip away pieces of flint. They used the pieces of flint to make blades out of them for cutting, scrapping and to carve onto wooden spears. They used these spears to hunt wild animals (e.g. elephants) for food. Homo Erectus also collected wild plants as another food source. These early people didn't have any clothing and artwork.

Homo Habilis known as the "handyman" existed from 2.5 million to one million years ago and lived in plains of eastern Africa (South of the equator). They walked slightly stooped down, had flatter heads than humans and had brains that were 2/3's the size of the average human brain. The adults average height was 1.5 meters tall. Habilis collected birds's eggs and wild berries for food. They also hunted wild animals and used sharp stones and heavy branches to kill them. The meat from the animals were usually eaten raw. These handyman built their shelters out of branches. During this time, Homo Habilis unfortunately didn't make or owned any clothing and artwork.
Many,many years ago, precisely 100,000 to10,000 years ago, in Europe, lived Cro-Magnons. These people walked fully upright and the adults were averagely two meters tall. They had high foreheads and had no chins. They have developed much including their usage of tools. During their time, they would use flint to make sharp-edged blades that could be used as knives, spear points, and chisels. Most of these tools were used to hunt for animals. They collected wild plants for food. Cro-Magnons built small huts for shelter but never stayed long. During winter, they had to build warmer huts because they had no clothes. These people were very creative because they did a lot of painting in their caves. Cro-Magnons tied animal hairs to small bones to make brushes, and the paint was made from rock powder and animal fat.
Cro-Magnon Man
Homo Sapiens Sapiens is another name for today's humans. Our kind appeared 10,000 years ago in Africa and existed till today in many parts of the world food source. We ate an abundance of various food such as fruits, vegetables, and nuts found in the environment. For example, we would gather seeds, berries, and roots found in bushes close to where we lodged. We also ate many meats from animals like fish. In our early stages we'd use many tools for hunting and fishing. During fishing we would use arrows, bows, and nets. we used stones, axes, knives, spears, harpoons, bows and arrows for hunting. We'd stay in huts during winter, and live in tents during the summer. Most of the clothing in cold seasons were made from animal skin and hides. In the summer, we would wear woven grass and tree bark.

The Development of Today's Civilization
Today's civilization started 10,000 years ago during the Holocene period. From this time the Homo sapiens sapiens evolved mentally and physically into today's humans. Here we learned how to write and make better tools and shelters.
