Who Are We and Where Do We Come From

There are many scientists who explain the theory of the Big Bang and the theory of evolution. They know what happened from 15 billion years ago until now. Those theories have influenced my religious beliefs. I would like to explain what the stories of the Big Bang and Evolution theories are. I would also like to give my opinion about the Big Bang and Evolution theories.

Scientists know that the Big Bang happened 15 billion years ago with an explosion of an infinitely hot, infinitely dense mass which contained all the matter in the universe. This mass is considered smaller than a marble. After the first three minutes of the explosion the temperature started to get lower, producing water. The universe was like a plasma soup. Scientists also know that thirteen billion years ago the force of gravity had started forming galaxies and clouds of dust started forming, stars, sun, the solar system and finally the earth.
According to the theory of the Big Bang, five billion years ago the Milky Way was already formed by a Super Nova explosion sending iron, carbon and oxygen into space. The basic ingredients of life which are carbon, water and energy, appeared through sun light that produced bacteria and algae. According to scientists, the beginning of the evolution of plants and animals which are bacteria, algae, fish, amphibians, reptile, birds and mammal was produced by a Blue Green bacteria that had oxygenated the earth’s atmosphere.

After all of this, the human branch diverged from monkeys four million years ago. The theory of evolution says that human beings are the result of an evolutionary process that began 4 million years ago with monkeys. The first branch that emerged from the monkey was the orangutan, then the gorilla followed by the chimpanzee. Additionally, Homo Sapiens appeared.

According to scientists, the first important species of the human branch was Australopithecus Afarensis. An example from this species is the fossil named Lucy. Another one is named Salem. Then, appeared Australopithecus Africanus. Raymond Dart found in 1924 the skull of an African child that was 3 million-year-old. Later on, appeared Homo erectus, who lived 2 million years ago. According to scientists, they had tools; they were the first to invent fire and the first to leave Africa. 1.5 million years ago appeared pre-Homo Sapiens followed by Homo Sapiens 1 million years ago. The last one was Homo Sapiens Sapiens. Neanderthals lived 50,000 years ago. A woman from Africa is considered the mother of modern humans and she is supposed to have lived 200,000 years ago.

In conclusion, the theory of the Big Bang and the theory of Evolution are very important sources to understand who we are or where we come from. Since I was a child, I just learned about the Bible and about God. However, now I can understand better the Big Bang and Evolution theories. I have concluded that those theories are better to answer many questions that human beings always ask than Genesis because scientists have a lot of evidence to prove that those theories are true. I like those theories more even though I still believe in the Bible.
