Keep going back on the evolutionary trail and you come to this point. How did such complex structures as nucleic acids and proteins come to be? One can't exist without the other. They are interdependent.

If you are referring to the ultimate origins of the first life forms, such matters are outside the scope of the theory of evolution. If you aren't referring to the ultimate origins of life, then I'm afraid that you've lost me.

If you are referring to the ultimate origins of the first life forms,

Yes, that is what I am referring to.

If that is outside the theory of evolution, which I would agree is correct but still a necessary point to consider, then a lot of people for a lot of years have misused the theory as 'proof' that life came into existence in a manner that can be explained as a fairly linear process from the prebiotic soup to the present.
