Many people in the world were divided about the reality of the existence of aliens or is it just a myth created by the human mind, and many theories appeared that support or refute the idea of the existence of aliens from outside the planet, and the question remains.. Are there aliens?.
A group of researchers provided an explanation for the reasons why aliens have not contacted or visited Earth so far, “if they exist”. The explanation is that there is no evidence of intelligence on Earth.
The researchers explained their idea that we did not send signals to deep space that could be detected only since the thirties of the last century only, and therefore those signals did not reach the aliens because the signals need thousands of years to reach, so they suggest that the aliens did not specify enough time to receive the signals and respond. on her.

The researchers confirmed that the signals emanating from planet Earth in the form of radio waves reached 15,000 planets and stars only out of the 400 billion stars in our galaxy, the Milky Way.
For his part, Amre Wandel, the physicist and author of the study, explained that only the stars that fall within the 50 light-year system have been reached by the waves and can have enough time to respond and respond to the Earth’s messages that were sent to the depths of space, as for the first signals of the Earth through waves. radio, it is difficult for aliens to respond to them because of their mixing and it will be difficult to distinguish them.
Wandel added that the theory of the study indicates that there are no aliens 50 light-years away from us, but it also does not rule out their presence elsewhere in the universe, and their lack of communication with us yet. They are waiting for signals from Earth to arrive, or their response to Earth’s signals is still in progress way to us.
The first message from Earth to deep space
The first intentional message was sent from Earth to deep space targeting aliens in 1974, and it was known as the “Arecibo” message, carrying simple information about the Earth and humanity, while there are plans to send another message carrying the solar system and drawings of nuclear urination and the form of male and female on Earth. Besides some basic sciences and mathematics.
