Children were told that no one really knows whether there is a god (though many believe there is); that people all over the world and throughout the ages have had different and often conflicting beliefs on the subject - and that they should examine every doctrine/belief system they come across using reason and then judge each one on it merits, according to whether the claims made can be supported by more than just "because it is written" or "have faith"?

If kids were taught to think and question rather than just accept and believe, I doubt any of the world's major religions (except perhaps Buddhism) would survive a generation.
