The world is what it is. A rock is just a rock. I tree is just a tree. Until we change how we look at things these things we see in the world will never change. We can turn these simple things into something complex such as a house. The house can also been seen as a simple thing compared to a neighborhood. And a neighbrhood is simple to a city and a state and a country and the entire earth. Everything can be broken down or built up into complex systems.
