Belief = knowledge ... nope.
'Just because a man is prepared to die for his beliefs, does not make them true'.
The burden of proof has most elegantly been summed up by Bertrand Russells Flying Teapot.

As for the initial debate... Atheism, why?
Personally, I find it very hard to believe that the world was created and is over seen by a supernatural celestial being, who spawned a son through a virgin wife (virgin? If I were Joseph and my 'virgin' wife fell pregnant... I doubt I'd believe God did it!). This son, could walk on water, feed 5000, heal the sick, and ressurect himself. Crikey, he makes david Copperfield look amateur!
Then theres the benign and gentle nature of God, who plagued his enemies, wiped out the Caananites, asked his believer to kill his son?
Further, I am led to believe that Satan is responsible for about 10 deaths in the bible, whilst God the Good is responsible for the deaths of approxiamately 2,000,000... world-wide floods, plagues, and tumbling walls of Jehricho... ho ho ho... nasty fella that god bloke.
Meanwhile, in the words of Douglas Adams "I really do not believe that there is a god - in fact I am convinced that there is not a god."
