However, in the specific case that "Libertygal" mentioned -- i.e.,
that ETs may take notice of the Earth among the other 100s of
billions of planets in the galaxy because she thinks our
"specialness" may make them take notice. However, I'm not
sure how they would know we were special (assuming that we
are special. I don't think we are, personally) just from analyzing
the spectrogram of our atmosphere.
I think you misunderstood what I was trying to say.
I was not implying our "specialness" drew any attention. Our discovery probably was most likely coincidental. I don't think anything we did, or our
radio signals, or anything related to humanity brought them here.
I would more be willing to speculate that liquid water, the design and make-up of our atmosphere, or perhaps even mineable minerals may have drawn
first attention. It could have even been one of our sister planets for reasons we are yet unaware of, and finding us was coincidental. Our planet
certainly stands out amongst our own just in unique looks alone.
What I was trying to say, and thought that I made explicitly clear was that the need to discover the origins of ones' beginnings would seem to be a
universal desire, regardless of the origin or age of the species.
Because, based on only the knowledge we have, we believe life began from some primordial soup, that conditions were just right, and things started
evolving, crawling from the sea, evolving more, then walking, a bit more evolving, then boom, mankind.
It is our quest in going to space, to find the origins of life, to gain glimpses back in time, to find the links to our beginning, proof to our
theories, and utmost - confirmation that we are not alone - though all common sense leans in that direction. We continuosly strive to go back in time
to the Big Bang, to understand how life, how we, got here. I think this is universal among all intelligent species, and is what drives the same space
exploration and chance discoveries of other civilizations.
Is it only a human trait to reach out to find others? I don't think so. Almost all species on earth reach out for companionship, most life on earth
does not survive in isolation. Why would we expect life elsewhere to do so? Life needs other life to reproduce and to thrive. Again, I think these
needs surpass humanity, and are universal.
If we were to find a civilization several thousands of years behind our evolution, say on Mars, would you expect that we would observe and learn, or
interfere? Would this mean we found them because of their "specialness" or because we were exploring Mars looking for signs of life? Observing
something once you find it does not lend to how or why you found it.
