Sure it is there too but I think there is evidence that it existed in many cultures long before the Christians wrote it down. A designer or god is a posited answer for the so far unanswerable question of origin and that question has been around for about as long as we have been asking questions.
I just mean that if the Christian narrative is inconsistent with what nature reveals that doesn't detract from the idea of a creator that is perhaps different from what is described in the bible.
Right on, you're right.
I think my misunderstanding stemmed from a divergence between the slight contextual difference, and the big conceptual difference, from there is a designer and there could be a designer. But I could be wrong about that too
