Viết một đoạn văn ngắn về ước mơ trở thành phi hành gia bằng tiếng Anh

I dream of one day becoming an astronaut to explore space. My mother used to say that the earth was just a small planet in the vast universe. My father used to say that the sun is a massive ball of fire filled with gases. Among the tiny stars in the sky, there are stars even larger than the sun. In the sky, there are not only white clouds, the sun, or bright stars; the sky is a vast space outside the earth that we call the universe. There are many mysteries beyond that space that humans have not yet discovered. I love learning about the universe. I dream of one day becoming an astronaut to explore space. I used to watch Doremon have an episode about the Jurassic Period on earth, where dinosaurs lived. Dinosaurs dominated the entire earth, they were the most powerful animals on earth at that time. But there was a collision (scientists have studied it), and it is believed that an asteroid or comet has crashed into the earth, bringing destruction to all living things on earth, and dinosaurs have gone extinct like that.
