Doug doesn't guess. He reads his Bible and knows the answer to all questions. Of course, no two Bible interpretations are ever the same ... but amazingly they're all the only correct one. Go figure.
"I" don't know the answers to anything. If it were "I" who wanted to embrace a theory I would (and did at one time) embrace the theory of evolution. However, being led by God's spirit inevitably leads one to reject the theory of evolution and leads one into all truth.
