I'm sorry if we can't agree on that God exist and is independent of the people who believe in it I don't see the point of asking such question. Wouldn't it be like making a omelette without eggs? we have to get the eggs first!
No, it's more like there being a painstaking recipe for omelettes with all sorts of complicated steps and rare ingredients, where no one has ever seen the eggs or knows whether they actually exist. The fact that the eggs may only be in some people's minds doesn't negate the existence of the recipe, and, for the people who don't think the eggs are actually out there, there is nothing ridiculous about discussing why they don't think the eggs will ever be found and why the recipe is therefore pointless.
And to expand just a bit on what Wheels just said:
2. We notice lots of claims of healings having taken place both in the bible and even in our our time. (The ones in the present often ignore the hard work of the medics though!) Now all sort of diseases and conditions are claimed to have been healed by some god or other - only amputees remain without ever getting a cure. Yours is a simple task - explain why you think your god will heal cancer patients (sometimes) and lots of other things but never regrow limbs.
It's not only
amputees, but that's a more concise title for the forum. To try to make it a bit clearer, Christians will claim miraculous cures for all manner of conditions, from headaches to cancer, after prayer. Any of these conditions can, and do, go away without medical intervention. Even more can be cured with
intervention, but that brings more complications to the question.
However, there are also other things such as the loss of a limb or genetic conditions like Down Syndrome which are never going to spontaneously disappear no matter how much prayer goes into them. This is what the name of the site refers to.
In a nutshell, it's an argument against the existence of god based on the fact that the only "miracles" we ever see are things which could happen by coincidence, while there is no evidence of prayer affecting conditions which are
