Seeing from afar applies here when aliens are checking us out from their perspective and not ours.

To whit.

For centuries, Earthlings have gazed at the heavens and wondered about life among the stars. But as humans hunted for little green men, the extraterrestrials might have been watching us back.

In new research, astronomers have drawn up a shortlist of nearby star systems where any inquisitive inhabitants on orbiting planets would be well placed to spot life on Earth.

The scientists identified 1,715 star systems in our cosmic neighborhood where alien observers could have discovered Earth in the past 5,000 years by watching it “transit” across the face of the sun.

Contact applies here does it not?

Great book, terrific movie without question.
