Contacts with aliens are somehow imperceptibly moving from the category of myths and fiction to the category of scientific facts. Moreover, in the West there are special statistics that clearly record all cases of communication between earthlings and aliens.
Let us recall several well-known facts about such contacts
1. The first scientific project to establish contact with aliens was proposed by the German mathematician and astronomer Karl Friedrich Gauss: to cut down a section of the forest in the Siberian taiga in the shape of a triangle and sow it with wheat. The Martians will see a neat figure through telescopes and understand that intelligent beings live on Earth.
2. Few doubted the existence of the Martians in the 19th century: in 1900, the Paris Academy of Sciences established a prize for the person who would be the first to come into contact with any extraterrestrial civilization except Mars.
3. The first encrypted message sent to the aliens contained only three words “Peace. Lenin. THE USSR . She was sent into deep space on November 19 and 24, 1962 from the Center for Deep Space Communications in Evpatoria during the Venus radar. The words were encrypted with ordinary Morse code.
4. In total, four meaningful interstellar messages were transmitted from Earth. The first - in 1974 - was sent from the largest planetary radar to date at Arecibo (a 300-meter antenna in Puerto Rico, USA). The power of the beam directed to the globular star cluster M 13 exceeded the radio emission of the Sun by 10 million times. In 25 thousand years, the Arecibo message will completely cover M 13, which consists of hundreds of thousands of stars. The signal was broadcast at two frequencies in a simple binary code.
5. If the pulses of one frequency are considered to be zero, and the other - as one, then a number of 1679 binary digits will be obtained, which in the plane is expanded into a spread of 73 lines of 23 points. It turns out a picture that depicts atomic numbers, a person, the solar system and the Arecibo telescope itself.

6. Three other interstellar messages were transmitted using a 70-meter radar in Evpatoria in 1999, 2001 and 2003. All of them were sent to nearby solar-type stars, the earliest of them will reach the addressee by 2036, and the latest by 2070.
7. The Earth has sent four spacecraft outside the solar system. The American probes Pioneer 10 and Pioneer 11 were launched in 1972–73. Voyager 1 and Voyager 2 were launched in 1977. In 40 thousand years, Voyager 1 will pass 1.6 light years from the star AC + 79 3888 Ophiuchus. "Pioneer-10" will fly to Aldebaran in 2 million years. All probes in themselves are proof of our existence, should they suddenly fall into the hands of aliens. In addition, they all carry on board records with drawings and greetings to aliens and even music.
