Now, that's the problem: How we perceive reality, methods of acquiring knowledge, and standards of evidence. Fortunately, we do have methods of inquiry and logic. Unfortunately, they are often discarded in lieu of confirmation bias, lack of interest in asking questions, and personal identity issues.
Since at least the ancient Greeks, we have the fundamentals of reasoning and the scientific method but even after thousands of years and many civilizations later we don't seem to want to learn. We still cling to primitive taboos, superstition, and willful ignorance. It's very frustrating to see a preference for old inadequate answers to some big questions. Many students aren't interested in learning other than the basic mechanics of a profession that will enable them to become rich... That's how most young college students perceive their efforts and expectations.
Perhaps it's only in the US where a highly advanced country with lots of scientific talent and research has such great numbers of people who are basically anti-science. That's why in several states (yes, where religion is the strongest) they're still debating about the validity of the theory of evolution--one of the strongest scientific theories we've got!
At any rate, for those of us who are awed by the richness of the universe and the thrill of scientific exploration, it's worth watching Brian Cox lecture at Ted. Enjoy--as I know you will.
