Recipes, instruction manuals, and blueprints are the hallmark of Intelligent {I.E. someone wrote the DNA code} therefore Life did not arise unaided, on its own, by purely natural means.
On the face of it, this is mere assumption - no more meaningful than simply asserting life didn't evolve. Can you prove it?
Also DNA is not a recipe, an instruction manual or a blueprint; DNA, combined with many other components themselves described by the DNA, forms a system than shares certain properties with those human concepts.
