Science is not capable of proving or disproving the existence of God. That's not good enough for the obscurantists. What they lack is physical evidence - any at all - in favor of their beliefs.

They look at the advances that science has made and the respect that many people give science and they feel many things, but one above all others - envy. They want their inane ravings to be treated with the same respect. After all, they deserve, because they, like, you know, exist and all.

The road of physical evidence has not worked out so well and so they need another plan - change the game. Enter "the wedge document." They insist that science has been hijacked by materialists who have caused the great ills of modern society. In fact, modern science didn't exist UNTIL its practitioners figured out they had to stick to physical explanation for actual physical evidence.
