Well, if you don't want to look at scriptures, look at nature, human nature, and history. In nature, everything revolves around light and dark--sun by day, moon by night...
The things the eye can see reflect invisible things or invisible light and invisible darkness which have intrinsic meaning for behavior, i.e., right and wrong.
What is right and what is wrong? A sun which produces light and life vs. a black hole that destroys light and life is an analogy. How do we as descendants of earth know what is right or wrong? A common guide is does what we do build something? create something? produce joy or sadness? or does it destroy something and add to chaos and confusion.
People can and have created as many gods or idols as they could imagine--even a coke bottle was used as an example in one movie. But does a coke bottle solve the little problem of where we came from, why we are here and where we are going? the dust to dust, ashes to ashes thing... does the coke bottle god create order, direction, or inspire peaceful coexistance? lead to inner peace? produce power that creates genuine life and light and joy and enlightenment?
And what about history? What are the lessons of history? Who were the Hebrews? Who came up with the notion of one God and why? Why did the Nazi's hate the Jews? or why do violent religious extremist fanatics hate Judaism? What were the lessons of World War II?
I would suggest that history revealed Judaism; Judaism revealed the coming of the Messiah; The Christian Messiah revealed the Spirit of Holiness and Truth; and that this is by divine design...
If you look at history and the ultimate credibility and witness of a united christendom, it is difficult to counter the divine design beliefs-- They can stand up to any test of faith or reason...
