Why do some scientists assume that intelligent life may be rare--that because only one high-intelligence--homo-sapiens (us) developed on Earth, that inteligent life is rare to evolve throughout the universe? Instead of seeing it that way, why can't you turn that thought around and assume that for every potential life-evolving planet, given sufficient time, there will evolve atleast one high-intelligence (human-level) creature among all of the other different (lower-level) species. that is the way i see it. given each planet(including ours) which goes through a long process of evolving many many different species, there will develop atleast one high intelligence, hyper-conscious being such as ourselves. that makes a bit of sense to me. the fact that we did evolve shows that high-intelligence is indeed possible! arent there any scientists who have this view? or anyone.
