I've pointed this out many times, and of course you're going
to pretend that you thought of it but, it's easier to find
alien life on distant worlds than to find alien visitors to
the Earth.

Think about it. Well. Not you but to the hypothetical person
who can think....

If aliens are visiting us then the are, at a minimum, taking
some measures to keep themselves concealed.

"Plausible Deniability," at the extreme least.

But when it comes to distant worlds, we know of no way to
hide the evidence of life.

Our atmosphere is filled with the "Biosignatures" of life on
our planet. Heck, at this point you can add "Technosignatures,"
the signs of an industrial/post industrial civilization.

You may refer to these technosignatures as "Pollution" if you'd
like.

Anyway, by analyzing the light they can determine the composition
of a distant atmosphere, and they can look for the tell tale
signs of life or even industrialization.

Okay, now for the bad news:

The planet they're talking about, this "Strongest Evidence for
Life," is over 100 light years away... 120, as the story puts
it. And, if true, the story is totally wrong when it extrapolates
this find into the abundance of life, and certainly intelligent
life.

So 120 light years away... the galaxy is maybe a thousand times
bigger (estimates place it anywhere from 100 to 150 thousand
light years across)... so a thousand life bearing planets, on
average, or so it seems... and none what so ever that can travel
to even neighboring solar systems.

We can't. And the algae they think is on this distant world can't.
