Some scientists discount any non-natural cause. Others stay quiet about primary causes but try to understand what has happened since creation began.

Issues of metaphysics, ethics and origins wind up on the back pages. It is too bad but that's the materialistic culture we live in.

Well, if you want you could certainly try to find some biblical imagery in our evolutionary path.
