oh you poor summer child, sometimes the world we live in can be hard to understand or to grasp right? i mean you do use your computer or phone the whole time? do you ever ask yourself of HOW a phone works? it goes a little bit in the same direction as to observation. you can look at the circutboard all day but without the proper education or science background good luck figuring out what each compond does. the world is too big to know everything that why some people study a field so much that they become experts. i think it is very arrogant to believe that you as a single person outsmarted all experts in a field that deicated their live to contribut to a field.
