a. "Evolution is the means by which life gradually developed from a single-celled entity into a human being."
This is science.
b. "God created the world in 7 days"
This is unthinking religious zealotry.
c. "God guided the gradual evolution of life, over a billion and a half years, from a single-celled entity into a human being."
This is NOT SCIENCE. It is religion, which is informed by the scientifically determined facts.
d. "Evolution is a purely natural process that has no influence from a divine being. The gradual evolution from a single-celled organism to a human being occured with NO influence from any God."
This is also NOT SCIENCE. It is also religion that is informed by the scientifically determined facts.
Both c and d are religion, not science. Both are entirely unproven and entirely unprovable statements of belief regarding real science. Science itself neither disproves nor proves religion... there is no statement regarding religion inherent in scientific inquiry.
The only thing that science DISPROVES is individual assertions and assumptions about the natural world that were put forward by people who believed the world is flat... The very few people that believe that every "jot and tiddle" of the bible was written by God could clearly have their faith threatened by science... but most people's faith has more depth than that.
