Evolutionary Biology is a very small part of an elementary education to begin with. My 13 year old sister is currently attending a private Christian middle school due to the wants of my parents. Her science education far out matches any public education because even though some aspects such as the beginning of creation are explained supernaturally, the fundamentals of science are still taught such as human biology, plant biology, chemistry, scientific method, etc. there is nothing wrong, in my mind, with allowing alternative views for the beginning of existence so long as each is held to the scientific method. The big bang, possibly the most widely taught theory for existence, is now being re-thought by the world's leading physicists, so why teach it as "fact"? I want the next generation to be open-minded and tolerant. One way teaching doesn't promote that.
Brevity is the soul of wit.
