Man - not as smart as he thinks he is

The more we learn, the more we come to find out that what we thought we knew, is in fact, what only what we believe. All of the laws, scientific explanations, and facts about the universe, which are so certain, continually change. A scientific law is only a definition to help our minds understand an abstract concept in logical terms. What we understand today will not be what is understood in fifty years. Yes, many of the same concepts will be the same, but new information will enlighten, change, and reconstruct the laws of today into something new. We need meaning in life, and so we give it meaning through words, definitions, and examples.
