Fermi's Paradox is that, to the best of present observations,
humans are alone in the universe as far as current telescopes can see. Despite countless stars & planets, none have (obviously) developed intelligent technological civilizations such as humans.
- prima facie, life never emerges on its own in our corner of the cosmos
Lots of hype recently about "sequential evolution" as scientists address the "
Gaia paradox" -- how
life has survived continuously on earth for such a long long time. Science acknowledges it is hard to explain how life not only emerged, but then afterwards
persisted, for ages & eons.
- even if life emerges, it probably doesn't persist on its own for significant time
Jared Diamond's
Guns, Germs & Steel argues that for civilization to emerge requires an amazing conspiracy of beneficial factors, all appearing on the same planet at the same place and time. Right region of the right planet with the right climate, with a perfect suite of plant crops (grains) that grow easily & quickly and act like a natural solar collector, harnessing starlight and converting it into useful energy. Plus the perfect suite of animals (farm animals) that can provide meat & muscle power to pull plows,
etc.
- even if life emerges & persists, it probably doesn't produce civilization, from the perfect storm of flora & fauna in the presence of an intelligent tool-using organism
So, here on earth there's a perfect conspiracy of factors giving rise, not only to intelligent technological humans... but also all of the supporting plants & animals without which we would have remained sophisticated hunter-gatherers but not civilized...
whereas everywhere else across the cosmos exists nothing but barren lifeless desert worlds uninhabitable.
Conclusion -- perhaps the disparity between "Jared Diamond's perfect conspiracy of factors" on earth and (
prima facie) "Fermi's Paradox of nothing anywhere else" suggests some sort of extra-ordinary, supra-natural God-like actor at work ???
