To see ourselves as others....

Here we are in our second technically inundated century, some of us scanning the skies for sounds or indications of non-human intelligent life.
How droll!, when, for many millennia, non-human intelligent life has been rife all around us. Some of these showing they have and employ complex languages which we still can not understand even a little of, whereas those who employ those languages display a ready comprehension of those of the humans.
Consider one of the species older than our own by many millions of years, the ravens and their near-kin, the crows. Every spring for the past nine years, a pair of nesting ravens who live in a nearby several-hundred-year-old oak near my husband and I sound as though they are teaching their newest fledgelings...something. Many and varied kinds of sounds do they use, occasionally mimicing other calls such as a dog's barking or a human calling-out. Are they teaching their language over three weeks' time? or are they telling teaching stories? outlining their philosophy, explaining what to look out for and when? How can we know?
Scientists have gone through the troubles of recording these "teaching" sessions of wild ravens in an attempt to decipher their language, the second most complex among non-humans which is vocalized (the dolphins' and whales being far more complex, utilizing sounds out of human hearing range...yet, can the ravens be employing some of those kinds of sounds as well? above and below humans' ranges?) . To date, no one has been able to decipher the least part of these non-human languages. The ravens' the dolphins' the whales' languages are all far beyond any translations of humans.
And what might they be saying about us to their youngsters? 'don't get to close to the mad almost furless apes, over there, they can be nice one day and try to kill you the next' ? How can we know? What unmitigated arrogance some of us have, to imagine we are somehow "superior" to non-humans when we can not even comprehend their languages, and they show they understand ours!
To see our selves as others see us.
And those others have been sharing livingspace with us for all the millions of years we have been here, and many more, before that we concocted relatively simple languages of our own...from listening to them?, such as the ravens in their trees, teaching their chicks, and we, still dragging all our knuckles, figuratively, (as naked apes who kill indiscriminately) still wonder what are they saying...
