Once upon a time, an alien spaceship discovered the Earth and sent a probe to it to establish communication with our civilization. And so, by the time of the second arrival on Earth, approximately 150 years had passed - from the end of the 19th century to almost the middle of the 21st. The aliens, to their surprise, see that the development of the Earth deviates from the norms accepted in our Galaxy for the worse. And they sincerely try to help, but so as not to interfere themselves - everything is in accordance with interstellar laws. And isn’t insight and another discovery the result of such help?
