Atheists rarely demand evidence that God exists -- because we know you
don't have any evidence. You just have your imaginary friends and hear
voices in your head. This is due to a well-known psychological
disorder known as schizophrenia.
The burden of proof is on those making claims, especially claims of an
extraordinary nature, such as the claim of the existence of an all
powerful, all knowing, eternal, magical creator being. Such a all
powerful being could do anything with essentially no effort, so why
couldn't this being communicate in a clear and obviously genuine
manner? Why is the Bible nothing more than cobbled together fables
written by men, edited by men, selected by men, copied by men, and
containing flaws and obvious fiction? A real GAWD could have just
presented Moses with a bound and essentially indestructible stainless
steel, chromium-plated manuscript. A real GAWD wouldn't need to fumble
through an evolutionary development process where 99% of created
species have gone extinct. A real GAWD wouldn't need to create a
universe of galaxies and billions of suns with apparently only one
measly planet supporting life.
