Arguments for God's Existence from Contingency

[datc]

The natural world is everything I've ever experienced, I cannot think of a thing which is not a part of the natural world.

My concluding paragraph reads:

These proofs relied on what I think is an uncontroversial principle that every contingent thing, including an actually imperishable one, must have a cause or perhaps "sufficient reason" which itself is necessary. We have by uniting in God what is diverse in creatures in the end demonstrated God's maximal creative power [as ex nihilo], an aspect of His simplicity [as God is being itself subsisting], His pure actuality, that He is the archetype of all finite things, and His goodness [as having caused the world through neither physical nor teleological causation but through self-diffusion of His goodness into being].

None of these 5 things is a part of the natural world.
