b . (God) isn't possible because "we" (scientific materialism or atheists) DEEM it impossible. ''
Just to clarify a bit, what you are talking about is PHILOSOPHICAL materialism, not scientific materialism. While there are some people who espouse that science disproves God, the VAST majority hold to the premise that "science is silent about God." Science deals only with the natural universe, anything supernatural is by definition outside its scope of reasoning. There are those that PHILOSOPHICALLY claim that there is no need for God (e.g. Richard Dawkins), and use the discoveries of science to bolster their claim. But those claims are NOT SCIENTIFIC in nature, rather a personal philosophy.
