Cloister is attacking the randomness assumption of Darwinian evolution by citing a published scientist--that you consider to be a wacky believer--and I consider to be the most unacceptable form of creationism possible: worse than atheism. I'd prefer no God at all to the God of intelligent design. I'm not sure enough about the patterns of evidence to embrace any form of Creationism--and I'm a lifelong Christian! Still, he's right. Randomness is not enough.
There are enough evidentiary red flags in the Biological theory of evolution to sic away believers and disbelievers of all ideological stripes. Since I believe, as a Christian, that God created everything, I'm hoping for a creationist answer in the experimental studies--but so far, no cigar.
The evidence rules.
