Haven't we been looking for non-material explanations for the last 30,000+ years? And with nothing much to show for the effort except some pretty pictures, stirring music and lots and lots of pain and blood, I might add.
Only in the last 300 years with the embrace of science has man progressed in every measurable way. Why, in god's name, would we ever want to go back to something that has been such a colossal failure for so long?
Religion had its shot at ruling man's mind. It failed. It's science's turn.
