Scientists from the American space agency NASA have explained the reason why humans have not met any aliens.
After a recent study, scientists of the American space agency NASA say that humans are unlikely to discover an alien civilization.
According to scientists, there is a reason for this, due to which the possibility of meeting humans and alien civilization ends.
The research paper stated that this is due to a civilization becoming highly intelligent.
He said that the end of an alien civilization is likely to happen due to excessive intelligence in its own hands, if we do not take steps, the same fate can happen to humans.
The results of the research have been called the Great Filter Theory, according to which there may be multiple civilizations in the universe, but they will destroy themselves before contact with Earth.
After this research, scientists have expressed concern that intelligent organisms like humans can cause their own extinction but can also avoid it and the only solution to avoid it is to work together for their survival.
