Unidentified….mmmm…does not sound very quantitative, but reporting something about nothing ALWAYS make a good story…like gossip.
Look at it this way…IF some entity had the technology to make it to Earth, then they would be so much more advanced than then the primative Human Condition that they would not waste their time observing us.
There is NO safety in numbers in terms of obervations…a Blimp in the fog can get as much as a 1000 “UFO” calls!! But hey…I got on the news cause I saw a UFO!!!
You want to hang out with an Ant-pile? That’s what we would amount to in comparison. And those telescopes looking for intelligent life? They ain’t pointed down here…
