Intelligent Life Elsewhere in the Universe

There are a great number of theories as to why human civilization has as yet been unable to make contact with other forms of intelligent life.

Sci-fi legend and public intellectual Arthur C. Clark offers a totally plausible suggestion here.  Just as ants (we believe) are unaware that they live among human beings, it’s perfectly possible that we don’t have the advanced level of perception and intelligence to know that some superior species is all around us.

Of course, Clark meant this as a “dig,” implying that, in general, the people of Earth don’t apply their intelligence at all well. Touche.
