I disagree with this statement. Do all the variables need to be quantified before any hypothesis can be formulated? If so, please name an area of science where strict adherence to this principle applies.
In all areas of science, calculations of probability are made based on the facts and not on things that creationists have made up.
A magician performing before an audience of evolutionists produces two royal flushes in a row. The crowd stands to its feet in applause proclaiming, Look improbable events happen all the time. A single statistician, knowing the probability of pulling a royal flush is (649,350 : 1) and twice is (421,655,422,500 : 1) stands to his feet and yells fraud. The statistician is immediately ejected from the assembly as being closed minded to the possibility of very real magic.
And if evolutionists were wrong about probability theory in real life, it would not be necessary for you to make up a fictional story to illustrate your point, because then your point would be true and you could illustrate it with something that wasn't made up.
Funny if the statistician was a creationist ...
For some reason, however, creationists tend to be pig-ignorant of statistics. Who can say why.
