The story of the biblical God and his dealings with humanity over history best fits reality as compared to other faith paths. The key is weaving in some of the unique things about the story of God as compared to other faith paths. For example, the evidence for the life, death and resurrection in ancient non-Christian literature that dates back to the time just after Christ is overwhelming (Jesus’ Resurrection and Contemporary Criticism by Dr. Gary Habermas).

Therefore, you can argue from rationality that the story of Christ can’t be a myth since the story was told all throughout Jerusalem - openly - where the resurrection occurred. Hundreds of eyewitnesses told the story - just after the resurrection event. Yet, no one writing from history at that time mentions anything against the reality of the story of the resurrection of Jesus. On the contrary, as Habermas points out, many ancient non-Christians wrote about the life, death and resurrection of Christ (The Historical Jesus by Gary Habermas).
