So; what kind of Scriptures could a believer in C use to witness to a believer in E, in order to get him/her to come to a saving knowledge of Jesus Christ?
People have faith in something because someone of authority, often a parent, convinced them that a it is true, despite the total lack of evidence for it. Someone educated about how the world works, cannot be convinced with a literal interpretation of the Scripture, because it is obviously false in a literal sense.
A knowledgeable person might come to have faith that Jesus is the Saviour, as I once believed, as long as their foundation is that the Bible has many unknowable mysteries and the details of Genesis is one of those. But once it is demonstrated that the Scriptures themselves demand a literal interpretation, then the house of cards falls apart and the knowledgeable person can believe none of it.
To answer your question, no Scripture can be used to witness to someone who accepts the facts of science, if the person doing the witnessing insists that every word is literally true.
