As long as they put the right answer in their paper examinations, whatever they believe is irrelevant.
As long as they aply the right way of doing things in their jobs whatever they believe is irrelevant.
If they can present the right arguments to answer and do what is needed (either at school or work) whatever they believe is irrelevant.
See, we believe, what we think we should believe, not what is real.
When something becomes real we don't believe, we know. Knowledge comes from practice and practice comes from... aplying what is "learned" - if learning is correct.
So , no learning is completely correct - with the practice, men learn to adjust to reality. That happened when sailors sailed and found out the earth was round, not flat. We need to be "very " patient with ignorance. The fact of people believe all creation was done in 7 seven days , although ridiculous should be tolerated, as long as that is not taught at schools ( that should be totally illegal, and treated as a felony). Common sense will prevail. Someday the hidden meaning of the 7 days will be unveiled . Then we will say creation was made in seven so and so . As of today that "so and so" is yet a too complex concept to be understood for almost every person , in current day.
But there's a hidden truth in that, obviously and we shouldn't discard that information either. Intelligence is also to take advantage of the old to live and interpret the new facts and knowledge acquired.
As of today we are are acquiring a lot of new information at an incredible pace. Advanced physicists have got a kind of knowledge of reality that would be preposterous for the average person. This is the plain reality. I mean there are multiple levels of knowledge and yet it works.
