①No one knows exactly how the earth began. ②According to a widely accepted theory, the universe began with a “Big Bang”. The earth exploded loudly and produced water vapor and other gases, making the earth's atmosphere. As the earth cooled down, water appeared and stayed on the surface. It was the presence of water that allowed the earth to dissolve harmful gases and acids into the oceans and seas, which made it possible for life to develop. First, the appearance of small plants encouraged the development of early shellfish and all sorts of fish. Next, green plants began to grow on land, which were followed by land animals. So reptiles appeared for the first time. Later, dinosaurs developed. However, they suddenly disappeared. After that, mammals came into being. Finally, humans appeared and spread all over the earth. However, they are putting too much carbon dioxide into the atmosphere, making the earth too hot to live on. ③So, whether life will continue on the earth will depend
