In a quantum multiverse life becomes certain even if the origin of life is extremely improbable.
An extreme level of improbability may be very sensitive to free parameters of the laws of physics.
If multiverses for all possible parameter choices exist (the "multi-multiverse"), we should exist in the one with least improbability of life originating.
If there is only one multiverse, with free parameters chosen, by "God", for whatever reason, then that value may not necessarily be the one with maximum likelihood.
If the observed likelihood is significantly lower than the maximum likelihood, then we can deduce that such a choice has been made (by "God").
