The greatest attribute an atheist possesses is the ability for reason. Provide an atheist with evidence and proof and facts and they will take on board what has been said and accept the evidence. Provide proof and facts to a religious body and it is dismissed out of hand instantly. I suppose we should thank our lucky stars we're not living a couple hundred years ago else we'd be burnt for heresy.
Jesus
Very little, if any, actual proof exists that Jesus existed. And then think about it: if a man came up to you in the street today claiming to be the son of the great creator, what exactly would you say to him? Exactly - it cannot be printed because children may be reading. Has everybody forgotten about David Icke?
Still, good ol' Jesus. He had his finger on the pulse of society. Though were he to turn up today and 'rebel' against the authorities as he supposedly did in his day, George W. would have him shipped off to Guantanamo Bay as a terrorist quicker than he could say a Hail Mary.
War
The history of the past couple of thousand years has been littered with war. How many have been based on religious beliefs? Let's just mention a few: the Crusades, Reconquista, various Muslim jihad's, the troubles of Northern Island, Thirty Years War, Muslim Conquests, Israeli-Palestinian conflict, etc., etc. How many conflicts have been the sole purpose of atheists? Answers on a postcard.
The Big Bang
Creationism is, quite frankly, the most absurd idea in the history of mankind. So much so that it is difficult to find somewhere to begin, since science has discredited the theory so comprehensively it seems folly to even discuss it. Instead I shall attempt to put my point across with a little story:
It was coming up to 8pm and little Johnny was being tucked into bed by his father. "Can I have a story, daddy?" asked Johnny.
"Ok," his father responded. "This story happened long, long ago. Everything around us wasn't here and then a man with a big white beard..."
"What, Santa?" interrupted Johnny.
"No, not Santa, he's not real." Johnny's face dropped. "The man I'm talking about is God. Anyway, he decided to spend six days creating everything we see today, before taking a day off on what is now Sunday."
"Six days?" said Johnny. "That couldn't happen."
"Well, it did," replied his father. "He created everything we have."
"Including dinosaurs?"
"No, not dinosaurs. They never existed. Forget all about them."
"Of course they existed, daddy. There's loads of proof. What about all the remains?"
"No. You're wrong. God did everything - and only 10,000 years ago. Therefore dinosaurs couldn't have existed."
"Daddy, don't be silly. 10,000 years isn't very long. The earth is four billion years old, at least. Scientists have proof. "
"Nope. They're all liars."
"Liars. So you're telling me everything was done by God."
"Yep."
"Then who made God?"
"Er..."
"Daddy, none of what you're saying makes sense. I know it's a story but it should at least be believable," said Johnny uneasily before going to sleep. "Have you been drinking again?"
Struggling to respond, his father agitatedly says: "Look Johnny, you're six years old now. Aren't you getting too old for stories."
"I was going to ask you the same thing," said Johnny.
