The probability of intelligent life appearing in the Universe and thus on Earth, can soon be calculated precisely by a quantum computer and will certainly prove less than 1 divided by the definitive number of exo planets recorded in all existing solar systems, probably several billion billion, proving at the same time that our visible and invisible universe is well finished even if it remains expanding like a big cake filled with grapes that never stops inflate in a perpetual heat oven. The only possibility of extraterrestrial life will therefore hold only in the unproven but highly probable hypothesis of the existence of other parallel universes.
