Объяснение:
There are a lot of planets in our galaxy, one of them is a planet called MARS. Many people think that there is life on Mars, while others believe the opposite. But there are also people who think that the atmosphere of Mars collapsed and people settled in the dungeons. As for me, I would love to fly to Mars, as I really love astronomy. I don't want to see what kind of soil there is, what kind of relief there is, and I would have met with aliens. I made friends with them and talked about life on earth. About the seas, about rivers, about lakes, continents, mountains, etc. Having talked with them, I would invite them to visit Earth, but first they asked to show me from the planet, put me in a flying saucer and showed all the beauties of their planet ... Then I went home and told everyone about my new friends, of course, no one believed me, but I know that we will definitely see you again.
