Is atheism a scientific perspective?

[Neo-Scholastic]

What strikes me as most puzzling about creationists and IDers is that they all would seem to lack the ability to ask themselves how it is that a universe which is sufficiently complex, so as to demand a designer, does not also in turn require a designer whom is equally if not far more complex in its understanding of relations and consequences, hence, requiring fulfillment of the same demand... which leads to a ridiculous, unbreakable chain of intelligent designers, until we are satisfied at the notion that such complexity is simply part of the emerging fabric of universes, at least one of which we do observe, rather than of gods, none of which do we observe.

Aquinas takes up the notion of Divine Simplicity in Question 3 of the Summa which I doubt many creationists or IDers have read or pondered. My understanding is that complexity arises from the great variety of deficiencies in contingent beings. It is analogous to a thousand different shards produced from a shattered crystal ball.
