It would be easy to "prove" that some such and such bacteria will devour the earth by "mathematically" showing how many times it divides. But such a "mathematic proof" would be meaningless because it doesn't take into consideration many separate variables.
I don't know the "Evolution is mathematically discredited" stuff you're talking about. But certainly not enough is known about the details of evolution theory itself for any such calculation to be valid.
The Creationism/ID movement reminds me of the people who argue that we did not send Apollo astronauts to the moon. They can come up with various attacks against the evidence that may sway some people. But their argument is still bogus on its face. Creationism argues AGAINST something, rather than FOR something.
The fallacy of Creationism (whether or not God exists is beside the point, as God could certainly have created Evolution) is evident by the methods of its adherents. Rather than affirmatively promoting evidence they generate, they attack the science of Evolution in an attempt to destroy it. Not unlike the efforts of the Communists in the 30's to destroy Capitalism out of some emotional sense that it was evil.
What? You've never heard of Freddy Hoyle? Where ya been? There continues work on the chances of the alignment of acids in the simplest bacteria etc, etc. The more we learn about the "simple" forms of life of which Darwin and Huxley were ignorant, the greater the odds against any evolutionary nonsense. But the odds are already less than statistical zero so smaller odds won't convince the thick-skulled evo thumper.
