I read somewhere that only 4% of the universe is observable and the remaining 96% is speeding away from us so fast that it would be impossible for a spacecraft to ever reach the horizon in any direction. There may be keyword advanced intelligence out there ‘somewhere’, but odds are it would remain so distant there’d never be contact.
Of the 1/6th of our universes’ planets, there may also be intelligent life on the scale of predator/prey relationships. But how many have copied a stable atmosphere, or the diversity of edible plant life and animals seemingly taylored to man, or the scale of the advancements that man has seen - from Magellan navigating the Pacific in 60ft ships to satellites navigating the solar system just in the last 500 years?
