SUMMARY (See detail below)
The probability of making the foundational DNA of the simplest organism, by chance, with all ingredients available, (huge assumption) is less than
Even a billion chemical reactions per second, extended over 100 billion of years, would only provide the following number of tries. According to standard mathematics of probability, if the likelihood of an event happening is less than 1 out of all the tries available it is considered impossible.
For comparison's sake, the probability of picking out one specific grain of sand from the sea on the first try is estimated as
