About the existence or not of the aliens, spoke on the SIGMA show "Front Page", Dr. Xenophon Moussas, Professor of Space Physics. 
As he mentioned, Science has been studying the object for at least 26 centuries. Lefkipos (Greek Philosopher) said that it is possible that some of the stars have some kind of life, he noted.
Today, he said, science is trying to study the possibility of life on another planet or on some satellites, such as the last spacecraft sent to Mars by NASA, and aims to find out if there is a species or not.
Explaining what we mean by "existence of life", he noted that it is something similar to what we mean by life on earth, that is, some living beings that are born, reproduce and die.
Asked to comment if there is life elsewhere, Mr. Moussas said that for decades the possibility has been discussed quite seriously and the answer that comes is that there are certainly many similar systems like the solar one, with at least one "earth" on it. stressed that some kind of culture has developed in the past or even now, we have almost no doubt about it, he stressed.
