Today, I learned about the history of the earth, from its birth to just before the present era. The Earth's birth is actually kind of a mystery because no one knows how Earth exactly came about. The most sensible theory is the Big Bang theory. This theory says that at first, the earth was made of gas and dust. Then, the Big Bang happened, and rain, oceans, and trees were made. From there, creatures appeared on Earth.
Bacteria was the first creature that appeared, and they made oxygen. Then, dinosaurs appeared, and mammals came after. After that, humans finally become part of nature. Maybe some of the animals that exist nowadays transformed from creatures from long ago.
I think that the evolution of animals are just as important to know as the history of Korea. Thank you for reading my essay.
