The Alien. Kyrgyzstan

The case, which was witnessed by a dozen and a half people, occurred in 1992. While climbing a steep slope at an altitude of about four thousand meters, the climbing party saw a thin, very tall human figure in a silver jumpsuit a little higher. 

The stranger's height was determined to be 3.5 meters. He was standing on a very narrow ledge. How he got there was completely impossible to understand. In front of him is a multi-meter abyss, behind him is a sheer cliff. He stood motionless and looked at the people who were getting up. Fear gripped them. 

The ascent stopped and began to descend. One of the climbers had a camera with him, but for some reason it did not even occur to him to take a picture. A few days later, they decided to climb the same route again, grabbed cameras and a movie camera, but the stranger was no longer on the ledge.
