That second quote you quoted from his link is very important. "Nowhere is the process by which God made, created or formed man set out in scientific terms"
Indeed, from the outset in Genesis there is no great explanations of how God created, but that he did create.
" in the beginning, God created the heavens and the earth "
Numerous indications of possible evolution are also in the text but also of immediate creation, however, no scientific endeavours seem to be there, basically - it seems it's God's business to him and he'd rather give us a story about what we should be concentrating on concerning him.
Only insisting on a literal and scientific approach to Genesis causes problems it seems, otherwise - I agree that there is no definite contradictions.
