@Gabriele_Corno This is obviously AI. The owls are two different species, and would never mate. There are other biological impossibilities, and the whole behaviour is absurdly anthropomorphic. Owls just don't think like human beings.
@engineers_feed It is not totally impossible of course, but the probability of two identical shuffles is so small that it is realistic to say that it has never happened.
@latestinspace To me the real issue is the probability of a technological civilization arising (a combination of f sub i and f sub c). We have absolutely no idea of this number. If it is less than about 10*-24 then we are probably alone in the observable universe. (There are about 10*22 stars).
@gunsnrosesgirl3 What is the meaning of 'exist', when referring to a physically disconnected place? With no connection in either time or space it seems impossible to know anything about them.
