Snowflakes, tornadoes, hurricanes all consist at a high level of order. Stars and planets as well. What you seem to be forgetting is that in between these items, there is a tremendous lack of order. Flip a coin long enough, and you'll get 10 heads in a row. The planet is billions of years old. That is a lot of time to flip a coin.
That is the argument I use... I accept any arbitrary value for the probability of the existence of "everything".
I then point out that the "coin flips" occur once every planck time (the smallest unit of subatomic causality - the speed of chemistry, as it were). these flips happen constantly, since shortly after the big bang.. about 16 billion years, give or take.
How many plank times in 16 billion years?
There are 1.855e+43 plank times in 1 second.
There are 3.154e+7 seconds in 1 year
There are 1.6e+10 years since (shortly after) the big bang
There were 8.0e+3010 Plank times (coin flips) since the beginning of the universe.
If someone says "the odds are a billion, billion to one" that X happened out of pure chance, then that means that X would have likely happened 8.0e+30 times (8.0e+3010 / 1.0e+100), which can said as "800 billion, billion times"
did I do that math right?
