Simply believing what you are told is acceptable and correct if you have no other information to connect to the information, AND you have not evolved your thought processing to include asking questions to enhance your understandings. This means you are still in the unborn child stage of being in a womb and fed by an umbilical cord of culture.
Even a child, once born, knows to investigate and keep asking questions until something makes sense. Then come back again and ask more questions as they gain experience and encounter different information.
