The designer is outside the box. It is in the box of time, space and material that it is obvious that a design requires a designer. The designer lives in the realm of eternity. He is a pure spirit, pure intellect, wisdom and energy. His reality and existence is different than ours is. It looks like we and everything consist because He says we do. The LORD said let there be light and there was light. Jesus is The Word and The Word became flesh. Everything is apparently made up of perfectly encoded information and He is the source of that information.
And yet variation and selection continue to happen, right before our eyes.
