First and foremost there’s the Rare Earth Hypothesis (REH), the suggestion that the emergence of life was extremely improbable for a confluence of reasons.
The theory essentially suggests that we hit the jackpot here on Earth.
Instead of saying that we’re nothing special or unique, the REH implies the exact opposite — that we are freakishly special and unique.
What we see here on Earth in this solar system and in this part of the Galaxy may be a remarkable convergence of highly unlikely factors — factors that have resulted in a perfect storm of conditions suitable for the emergence of complex life.
“One generation passeth away, and another generation cometh: but the Earth abideth for ever”. ~ Ecclesiastes 1:4
