Aquinas' Five Ways - The Best and the Worst

As discussed in class, St Thomas Aquinas was the first Christian priest to start Scientific Revolution. He attempted to prove that by using reason correctly, one would be brought closer to God. Unfortunately, his proofs were loose and errors were abundant.
I think his worst proof was the First Way : the Argument From Motion. This explained that since everything must have a mover to start the action, then there must have been one unmoved mover and this was God. As Will pointed out in class, Aquinas is "begging the question" by stating his argument already assuming that it had been proved. It also brings up the question, who moved God?
Aquinas' best one would probably be the Fifth Way : The Argument from Intelligent Design. I find that it is rather hard to think that a clump of atoms just exploded to make the universe according to the Big Bang theory. I find it a little easier to think that there is a super being above watching over us. it seems like a security blanket and sometimes even a scapegoat for us to fall back on. So, i don't really know how to argue how the universe was made because it does seem like nature has its way to work.
