Hey ChuckMo,
I think you need to go look up "rational" again because anyone who believes in a metaphysical superbeing is quite a stones throw from rational...but, I know, belief in the aforementioned superbeing feeeeeeeellllllssss alot better.
I wish those "idiot" objectivists would desist in the use of their naturally evolved brains!
Well, lets take the Godless view of the universe to its natural conclusion when considering rationality.
The universe started with an uncaused random quatum event. After billions of years of Newtonian physics, Einstein relativity, and quantom mechanics... The four laws of physics randomly devloped our galaxy, later through random events our solar system and finally our earth.
Randomly the atoms of the first life form assembled which randomly started to evolve, recently the atoms of your DNA assembled. Through quantum probabilities and chance your brain's nuerons are firing in such a way for you to have the thought that there is no creator. The atoms in your brain are giving you the illusion of Aristotle logic only by chance.
One can only conclude the reason for your philosophical leanings have happened through a huge amount of random events. Starting with the big bang. I don't think I would let my philosohical outlook be guided by the premise that I think what I think through billions of random events and probabilities. However that is one's constitutional right. Be careful, sometime through some other quantum events your view may change.
Note to anyone who responds to this: I'm not particularly interested in getting into a debate. I'm really just wondering what the standard non-theist response is to this sort of question.
