Axel,

I have no idea what is out there in the universe, but I am not so proud to assume that I can possibly imagine all the ways that life can exist in the universe, let alone how life can even exist on Planet Earth. Have we not found life on this planet in a multitude of places where, at one time or another, we would have said that it was impossible? At the bottom of the oceans? In 800 degree waters? In and around rocks found miles below the surface? If we keep finding life here in places that have no bearing to the Goldilocks Zone, why should we not assume it is in hundreds of other places that seem equally impossible?

Why haven’t we heard from another intelligent species? We can barely communicate with the species on earth. The squirrels in my backyard are smart enough to shout to each other the instant I throw any food out there. I can hear them talking to each other. I can hear them screaming whenever a hawk is flying overhead and they all disappear. Nevertheless, we can’t communicate with them or any other species on the planet on their own terms. How can we hope to communicate with anyone else? Besides, if they were really smarter than us, then surely the Emmermann Threshold would teach them to stay away lest we screw them up too.

Ancient Aliens, Alien encounters, and such... The longest stable chain that one can form with silicon is 8 atoms long. Not nearly enough for life... The hybridization of carbon is what makes life, nothing else.

While conditions today may not be favorable for life, who's to say they werent in the past. The article simply indicates what scientists should look for in the way of life that may have evolved when conditions were still favorable. I don't think there were ever "Little Green Men" on Mars. Maybe elsewhere in the universe though. I'd love to know what kinds of minerals they're collecting. 🙂
