Why has not the human alien contact

There are countless planets of the universe , may also have a myriad of civilization, but we never found out why the aliens ? This is a problem physicist Fermi (Enrico Fermi) 60 years ago.

An attempt to answer this question is to explain the Great Filter: a planetary civilization leap into interstellar civilization is very unlikely , because perhaps intelligent life is extremely rare , and perhaps intelligent life tends to self-destruction.

Last week, scientists reported the discovery of a planet ‘s ” twin brother ” Kepler-186f, its orbit is located in the habitable zone of stars , 10% larger than the Earth , liquid water may exist , there may be life . Kepler space telescope discovered thousands of exoplanets or candidate planets, which are located in multiple pieces habitable zone super- Earth planets to support life is not uncommon .

But if Kepler-186f really intelligent life , is not good news for humans , because it strengthens the Great Filter explanation , suggesting that humans and their alien companions are facing catastrophe.
