With life being so fragile, and complex, I do wonder about the statistical probability of everything that led to it, and that sustains it, arising by chance.
Would it be one in infinity?
In other words zero? (1/∞ = 0)
While the existence of life forming spontaneously is admittedly small if considered as a single (one-off) event, most creationists don't consider the incredible time-frames that are involved in the life-history of the Universe PLUS the absolutely massive numbers of stars and planets in existence. Considered in that light, the odds of such a chemical event occurring increase to the other side of the scale, where it's relatively improbable that life WOULDN'T evolve in the Universe elsewhere.
Another mistake is thinking that the evolution of life is a 'one-off' event where the changes are not cumulative (not time-limited), but that life must spontanously appear as a complex multi-cellular organism, complete with DNA/reproduction and other organisms with which to mate! That IS incredibly impossible, and the reason why NO CREDIBLE person (much less a scientist) would expect it to occur: it violates all known physical laws. Hence why Dawkins went to the extreme lengths of even naming one of his books, "Climbing Mount Improbable", a reference to the fact that while you cannot climb a mountain by approaching it from the cliff face and jumping up to the summit, you CAN get to it's summit rather easily by approaching from the gentle ascending slope on it's back-side.
NOW, compare that thinking to that needed to believe in God of the Bible: this incredibly powerful and complex being didn't have a beginning or end, but just always WAS; he'd have to be magnitudes more complex than the life forms He created, as He had the power to cause ALL LIFE to magically appear by word of mouth, alone, by speaking "Let There Be".
So, which scenario is MORE improbable? The former, or the latter?
Theists make the mistake of falling for the fallacy of discounting the improbable and accepting the even MORE improbable (or, the completely impossible).
It's like saying that the rational explanation doesn't suffice, due to probability: so let's just accept the impossibly-impossible explanation instead!
It's goofy reasoning used by people who clearly don't understand statistics and probability, but it IS quite successful: people fall for it, as the reasoning is bolstered by appeals to tradition ("well, my Grand-Daddy believed in God, so it's good enough for me!"), appeals to popularity ("we have 100 million believers in our church: they ALL can't ALL be wrong!") etc, etc, ad nauseum.
