What's the specific quote related to that?
As far as I'm aware, his argument is that there are implausibilities in evolution theory that are better explained by creationism.
I accept that his beliefs probably colour his opinions, but am unaware of any religious references in his published scientific work.
God making the earth in 7 days is as central to creationism
as natural selection is to evolution.
you could pretend you dont think god made the earth in 7 days while spruiking creation theory,
but that would be like pretending you dont think Dustin Martin was important, while regaling the merits of our 11th premiership.
