Scientists, theologians, teachers and everyone else believe things that are taught them without thinking. They figure that the people who taught them should know, so they don't delve into the subject for themselves. But just because they have degrees doesn't mean that they know everything about the subject. For instance: I was prescribed a drug that was, according to the learned doctor, non-addictive. But he wasn't as smart as he thought he was, because I became addicted to it. It took many years to get off it, but now I know to think before I blindly follow someone's instructions. Man was created with a mind and a 'thinker,' we should use it for ourselves. If you will think about it, there is always at least one more step that the brightest mind is afraid to take.
