Why? Do you perceive design in the cosmos?
Not in the physical universe, no. It is a machine that would go of itself. The intentional design, I believe, rests at a higher level, one of mathematics. The universe as we see it, and perhaps even the laws of physics themselves as the universe obeys them, are but one instantiation out of an infinitude that would conform to the Divine Will.
It's a question of epistemology vs. metaphysics. From God flows math, from math flows physics, from physics flows the physical universe. God wouldn't be so unsubtle as to reach past math and physics to press his thumbs into the clay, that we might trace his fingerprints. Reason dictates that there are no such seams in Creation.
