<blank> could not have caused <this>.One side fills in the blank with the theological category "God" with <this> referring to the various baroque strangenesses, alleged inefficiencies, and anthrompomorphized cruelties of biology.
The other side fills in the blank with the scientific category "random processes" with <this> referring to the tightly-integrated information-processing molecular nano-machinery in the cell.
Yet the first side is considered "science" and the second side is considered "religion".
Or consider: One side asserts that all began in unorganized, unguided primordial Chaos, with our actions and thoughts governed by the motions and positions of inanimate bodies (stars and planets or atoms in motion, either way it is an astrological outlook).
The other side asserts that Reason, Wisdom and Knowledge were prior to all else, that the Cosmos is therefore rational and able to be rationally understood by intellects that have the radical ungoverned-by-brute-matter freedom to draw conclusions and pursue the truth.
Yet the first side is considered rational and scientific, while the second side is considered to be a throwback to ancient superstition.
