Creation vs Evolution

Kind of the discussion I'd hoped we'd have had last night, so I clicked the next blog button, followed a link on the page and ended up here:

which has another interesting take. So my question is "If the theory is too general to be considered scientific, and has a considerable number of devotees, does that make it a religious belief?"
