If we obtained a good understanding of the beginning of life and found that the odds of life occurring at some point in our universe was one in a million, then what exactly would follow from that. Sure the Fermi paradox would be settled, but would this give credence to multiverse/big world theories or does the fact that the information is anthropically biased tell us nothing at all? Finally, if we don't have to suppose a multiverse to account for a vanishingly small probability of life, then wouldn't it be surprising if there are not a lot of hugely improbable jumps in the forming of intelligent life?
