The problem with the math is that, while it is probable that given the sample size, a trial and error such as life could occur on one or several planetary objects; the probability that this chance happens over and over and over in the same place to create even a simple life form becomes less and less probable with each generation.
I would have problem from a mathematical perspective agreeing that something like DNA evolved. When you mix in something like just the right size asteroid hitting earth, producing a moon, that in turn paved the way for various life forms to evolve, the probability becomes so slim that it is beyond our comprehension. I find it ironic that in one of the parent posts leading to this thread, the poster refers to humans as somehow believing they are intelligent. Yet we have not found a better explanation of our occurance other than a train of events that is mathematically impossible.
