what's on mars? There are Martians? There are large buildings? Have a house? Some scientists think that there is life on Mars, and I also want to go to Mars to play.

one day, I was having a class at school when a round UFO came to the playground. Suddenly, a strange light came into the classroom and sucked me in. Let me take a closer look. Isn't this a flying saucer? How did you come to the school? I saw a flying saucer shining silver, like a giant dragonfly. The top cover of the flying saucer suddenly opened and I went in. The setting in the flying saucer is really strange, with computers, satellite locators and life detectors. A second later, I came to an unknown planet. I saw a sign in the sky that said "Welcome to Mars!" The words. Ah, so I'm on Mars. Looking at this strange and beautiful planet, I have an unknown feeling. When I came to a city on Mars, all I saw were strange people: some had triangular heads and round bodies; Some people have square heads and oval hands; Some people have round heads and square legs; Yes ... I didn't know they were all Martians until they introduced themselves. They sent me many things, such as: machines that can make clouds into various kinds; An invisible cloak that can make people invisible; A flying monty carpet that can take people to the sky; Machines that can make people bigger and smaller. Martians also want me to bring other earthlings to visit this beautiful Mars to make it more lively.

when I went back, I found that Mars was still a deserted land, which had not been developed by human beings, and the Martian city and Martians had disappeared. Whether there is life on Mars is still being explored. Is this a reality or a fantasy for the future?
