Since nothing with extension in spacetime can have always existed, anything with extension in spacetime has to have been caused to exist, energy included.
You've gussied up Anselm with scientific language, yet you've committed his fallacy of special pleading.
Actually, his syllogisms are Thomistic.
I first read it inhttp://en.wikipedia.org/wiki/Ontological_argument#Anselm.27s_argument , Anselm.
You may wish to call it "Thomistic", or what-have-you. I call it bs, because it's an example of special pleading.
It'd be nice if you addressed that aspect, but I'm sure you have some meeting of world-famous theologians to attend, or something.
