Pigs fly. Someone with a blackboard behind him (Dartmouth philosophy prof Marcelo Gleiser) says something sensible on Earth’s uniqueness:
The bottom line: Earth is not mediocre.
If life is out there (and there is no good reason why it should not be), it will most probably be simple. If there are intelligent creatures in our galaxy, they are likely so far away as to make us effectively alone. According to this view, which I call humancentrism, modern science is telling us the opposite of Copernicanism: as molecular machines capable of self-awareness, we matter because we are rare; our planet matters because it is rare.
Copernicanism (Earth is NOT special) was popularized by Carl Sagan, apparently in part to promote belief in many alien civilizations. A view best exemplified in the Drake equation.
