Bloodshadow's answer are very good. (though the final paragraph of his post means 4th when it is saying 5th)
Oops. I do mean the fourth. I'll fix that now.
What has the power to start a contingent being moving?
The Big Bang, of course. For reasons we do not yet understand, the Big Bang starts off all the energy in the universe in a state of extremely low entropy, and the second law of thermodynamics continues from there. Maybe God made the Big Bang happen, maybe not, but a God definitely isn't necessary even according to our current understanding of physics.
Besides, a "being" here is very ambiguously defined. Everything in the universe is made of a collection of various elementary particles (mostly up quarks, down quarks, and electrons), which are actually waves on the quantum scale. It is a direct consequence of quantum mechanics that if I replace one electron in your body with an identical electron,
literally nothing would have changed about you. None of the atoms in your body are the ones you're born with. In other words, "you" are not the atoms your body is made of, but rather a
pattern of atoms. If I break you down completely on the atomic scale, then reassemble the pattern that is you out of a different group of atoms, you would still be you. Nothing would have changed. No, I do not believe in the existence of souls, and I will not argue about it here.
My point is, all "beings" in the universe are patterns of elementary particles, rather than the particles themselves. It's like the difference between a pencil drawing and the carbon atoms that make up the graphite that displays the pencil drawing. The patterns do not move; the elementary particles do. So if you're going to talk about "beings" and how they move, at least do so rigorously. Otherwise it won't mean anything.
Also, perfection is, philosophically, the complete fulfillment of somethings nature. This is the maximum fulfillment of a things nature, therefore it is perfect.
What is a being's "nature"? Define it rigorously, in the context of modern physics. If you don't, then you're just throwing around words that sound vaguely meaningful but aren't really.
For the argument from design, we know that each being has an inherent goal based in the nature of that being. We do not create the goal out of nothing, the goal is based on the nature of the thing. Therefore, there has to be someone to create that nature (aka God).
Why does each being have to have an inherent goal?
Humans do not necessarily have an inherent goal. Yes, humanity has a disposition toward survival and reproduction. On one hand, you could say that God created humans and gave them the disposition for survival and reproduction. However, that's by no means necessary. It could have been pure chance that we obtained our disposition toward survival and reproduction, from evolution. Because if we didn't,
we wouldn't be here to wonder about our disposition toward survival and reproduction in the first place! That's the anthropic principle. If something seems like it's made just right for our existence, it does not necessarily mean some higher being designed that way.
