Metaphysical
Metaphysics deals with the nature of transcendent reality. Unlike physical theories, which deal with matter and energy, metaphysical theories cannot be tested through scientific, empirical methods because they defy the laws of nature.
Understanding metaphysics is important because the scientific conclusions regarding the origin of our universe in the early 20th century forced materialists to abandon our known reality and venture into philosophical speculation as to how everything, as vast and complex as our universe, sprang into existence from nothing.
While multi-verses, parallel realities and 13-dimensional space-time hypotheses sound like science fiction, they highlight the lengths that materialists have gone, to conjure up super-natural causes for our origin. It seems quite clear that as long as these theories do not invoke a divine creator, they can be 'reasonably' considered a possibility for existence.
Rather than seeing the creation in need of a creator, these who venture into metaphysical speculation only kick the can down the road, begging the question that more universes and more dimensional realities only make the necessity for an intelligent designer, outside of time and space, even more plausible.

If everything that is created needs a creator, then who invented God?
