Cosmological fine-tuning for the existence of life is so well established that it is essentially beyond question at this point, unless one is willing to put blind faith in wildly-fantastic speculation about an infinitude of in-principle undetectable alternative universes. A huge amount of complex, specified information was clearly infused into the origin-of-the-universe process.
Not only did matter, energy, space, and the physical laws of the universe come into existence at this point, but time itself did as well. This means that the cause of the universe must exist outside of matter, energy, space, the physical laws of the universe, and even time.
This raises an interesting question about design and temporal supernatural intervention: If the source of the universe exists outside of time itself, does the objection of “periodic temporal intervention in the affairs of the universe” even have any meaning, from an outside-of-the-physical-universe’s-unidirectional-time-line perspective? In other words, from a perspective that transcends time itself, is there any difference between the moment of the creation of the universe and any other moment in the history of the universe?
