The next theory after Evolutionary Theory will be Intelligent Design, not religion. Should Intelligent Design turn out to have mathematical and/or evidential flaws, then it will be replaced by yet a newer theory, and so goes forward progress.

The whole sordid story is here: The Evolution of the Discovery Institute's Website Rhetoric.
You want more? Read Dembski's Mere Creationism. The whole scheme is exposed there, and none of those authors will ever be able to testify in a court of law, under oath, that intelligent design is science rather than religion.
