Will beings find intelligence on Earth?

Astrophysics and astronomy are two somewhat overlapped and yet, completely different studies of our galaxy, our universe.  Distances are measured in light-years, not miles. We are looking at all of the bright dots in the sky, stars, to determine if they might have life and intelligence. 

My understanding is that there can be life but no intelligence, for example, a plant or a growing tree. That is life; lacking intelligence. My assumption is that if astuteness is found, you will find life.

Does it not seem possible that there is some form of perspicacity way out there that could be studying us? 

How far is way out there? A light-year is how far light will travel in one year.  The speed of light (in a vacuum) is ≈186,000 miles per second or ≈669,600,000 miles per hour or ≈19,070,400,000 miles in one day or ≈5,869,713,600,000 miles in one year. 

The circumference of the earth is 24,901.461 miles.  If a light-year could be bent and made to circumnavigate the equator, there would be 235,717,639.2 layers of light.  Wikipedia states a light-year equals 5 X 1012 based upon the Julian year of 365.25 days in a year.  Another interesting tidbit is that the light from the sun requires eight minutes to reach the earth.

If there are little green men or beings with Hubble telescopes studying us, we know they will find life; will they find any intelligence?
