>>>Why do people think Darwinism is a perfect creation?<<<
Talk about your rhetorical straw men. Sheesh.
Science explains the mechanics of the universe, nothing more. Religion explains the meaning of the universe. In fact, the body I’ve received is filled with bad engineering and poor wiring - my back aches, my vision is lousy, my big toe is prone to hangnails. Some foods give me gas. Certainly a designer could have done better work.
My soul is another thing completely, though. I think C.S. Lewis, in response to a question about whether our body had a soul, said something like, “You are a soul. You have a body.”
Scientism does not work very well for explaining original sin either. Back aches, hangnails, and infirmities are covered somewhere between Genesis and Job.
Not the design, but the Fall.
