Boy, this turned out predictably.

Let's condense pages of argument into a really simple rule of thumb: since there's no way to definitively proof or disprove the existence of God, there's no point in arguing about it. We'll all find out after we die, so let's focus on more practical things that we can measure and find tangible. 

Since the topic is about if church and state should be separate or not, the more pressing concern is balancing human rights and freedoms verses preserving religious customs and traditions. It makes more sense to me to discuss that than if the Big Guy in the Penthouse in the Sky is real or not. I am much more concerned about what His followers are doing than if He exists or not, considering there's the whole cherry picking what to follow out of the Bible or Qur'an or Torah or whatever to impose select values on entire groups of people. I mean, when you have one Church saying one thing and then the one down the street saying another, it doesn't exactly inspire trust in one leading the government if they can't even agree with what's legitimate or not.

But seriously guys, you aren't accomplishing anything by debating if God exists or not because nobody's changing their minds. Agree to disagree and move on.
