Evolution is probably the biggest dichotomy that youths face as science in schools rarely agrees with the truths of the Bible. Seeing how the kids are in these learning environments longer than any other form of supervised education, it shouldn't be a real surprise that the kids fall away from believing the "stories" they were taught as kids. "Real" science happens in academia, so they think because this is all they know. I had a 10 year old neighbour come up to me and challenge me that man came from apes and not God because her teacher said so and why would the teacher lie, etc... so sad to see the innocence ripped away fro these young ones as they are indoctrinated into satans kingdom.
