There must be a lower bound the probability of abiogenesis from random particle interaction. So take the simplest self replicating organism. How many atoms does that organism has and how likely would a bunch of those atom end up in that particular configuration. You can also specify the upper bound we know several planets that don't have life. So we have a rough measure on how likely will the planet to not have life. So from brute force random atomic interaction. If probability of abiogenesis is 1/n then n-1>infinity-n. n must be a finite number.
