I ran across this quote from websnarf on youtube. Thought it was one of the best I have seen. Here is his page: http://www.youtube.com/user/websnarf
"With "god" there is no way to understand anything by my own efforts because god might be faking circumstances. There is no way for me to even know that I am in control of my own actions, because god might intervene or be tricking me into them. And accountability is meaningless since any action may be part of god's plan and punishment may come arbitrarily.
Without god, the world makes sense, because one can reason, understand, act and be accountable in a way that is reconcilable with the world, with logic and with my ability to deal with those things. With god, I have nothing but doubt, unaccountability, guilt for no reason, and no reason that I could be sure of."
