No one can ever disprove God. That doesn't mean the likelihoods of there being or not being a god are equal.

For instance, no one can disprove that I'm going to win the lottery today. That doesn't increase the likelihood of me actually winning the lottery.

Although we can never rule out the Abrahamic God of Jewish, Christian, and Islamic faiths...we can rule it out as much as any of the other Gods various cultures have worshiped throughout history. Indeed, Mount Olympus is just as unlikely as the Christian Heaven. There's just as much evidence for both.

Intelligent design is bullshit. The Bible is bullshit. Neither should come anywhere close to a school.

Just READ the Bible...that will give you more proof of it's bullshittiness than any atheist could. Just try reading it. Not just Psalms, either. Or if you're not reading it literally, how do you pick and choose what's right? Why not cut out the middle man?
