I vote neither, just teach the facts and let people draw there own conclusions! We should teach what we know, not what we think we might know. If we don't know say "We Don't know", or that is currently being studied. You could teach any science all the way through High School and there is enough to keep you occupied without having to get into either!

PS Parents or college professors should teach Faith or theology, respectively. This board is proof that this is a life long endeavor.
