The facts are not scientifically in doubt. There are a dozen or so physical constants (the strength of gravity, the size and charges of fundamental particles, etc) which control how our universe has developed since the big bang, and if some of them had been even a little different, the universe would have collapsed back in on itself long before now, or flown apart, or have remained a thin soup without stars or planets.
It makes some people think that the probability of all this occurring by chance is so small that it must have been designed. But others argue that the logic is all wrong and probability doesn't make sense in this case. How does the argument go?
