Explain to me the sudden appearance of existence from non-existence during the big bang without relying on faith. How is it that you can defend the impossibility of energy-creation in one sentence and assume the creation of all energy from nothing in the next? Even if it were another part of an unknowable cycle it would eventually have some origin. Even if you suppose a reality outside the literal comprehension from our relative observance you are literally admitting the existence of the supernatural and cannot make any claims on how it might affect the present. Even if you discount the prior existence of 'time', thus invalidating any concept of a beginning or end, it's a simple Boolean value. Existence of any form equals 1, or it equals 0.

The Standard Model can make sense up until the very instant before its creation, where it offers no answers. There is nothing but the faith that your model is born of nothing but became everything, or that the supernatural exists but is now nothing.
