We have a saying in the nation that goes, "Don't take things on face value". I once heard a God say that the only thing we truly know is what we experience. Do you agree? Now, this is interesting since we can't possibly all experiment on everything to get results. At some point it seems that we do accept things on face value. Have you been to the sun? How do you know how far it is? How do we know how fast the Earth travels? Mathematics of course! When children have a question, they have an interesting way of asking, asking and asking some more until you just want to say "Because it just is!". Is that the correct response to give? I've been interested in hearing others build on face value. Do you or don't you take things on face value? And if so, at what point. If now, How come and what do you use to show and prove what you "know"? Feel free to give examples and experiences.
