Guessing like "if every 100th planet is habitable" or "if every millionth planet is habitable" is just useless, until we know the real chances. Maybe the formation of life is so rare, that even happening on a single planet of the universe was incredibly unlikely. Or maybe not. Or maybe it is something that can only happen in this particular fragment of the universe. For example in Asimov's novels, humans were alone because Earth's huge moon, and radiation level, that were both discovered to be galactic extremes, both sped up evolution. Can we say if in real life, these stats are extremely rare, or just somehow rare, or average? Not really. |
E.T. was based on a true story. In your face!!
