There are many versions of the mythical story of human origins. The following is one of the more traditional and widely accepted stories: In ancient times, the species of life on Earth were very diverse, but only a few of them could adapt to extreme environmental conditions such as living in cold or hot areas. These creatures that adapted to extreme environments gradually became extinct, and the species of life on Earth began to become more and more singular. As time passed, the species of life on Earth gradually evolved into the first humans. According to legend, the ancestors of human beings were a kind of creature called "hominoids". They had a highly developed brain and powerful thinking ability, capable of complex thinking and behavior. The hominoids gradually evolved into the first human beings. They began to explore every corner of the earth, discover and use various resources to gradually establish the first civilization. As time passed, humans evolved into a more advanced species. They began to master more knowledge and skills, developing more complex social structures and cultural systems. In different periods of history, humans have experienced many wars and cultural conflicts, but as time passed, humans gradually lived in harmony and established a prosperous civilization. This was a mythical story about the origin of mankind. It described the gradual evolution of human beings from primitive biological forms to advanced species and the establishment of a prosperous civilization.
