Dr. Craig is a liar.

How would our reality be different if it wasn't created by an intelligence? How would we tell the difference?

If someone can't answer that, then all they are doing is making an unnecessary assumption, due to their own incredulity.

If they can answer it, I'd love to know where they're getting their information from. Of course, they will try and talk about subdivisions of our reality, and then try to extrapolate the qualities they have to reality itself. The fallacy of composition. Qualities of parts do not necessarily equate to qualities of the whole; especially when we have no reason to believe we even have all the parts to study yet.
