The Brain
"The brain is like a tree; it starts out as one root, grows with core knowledge, and shoots off in different subdivisions of thought. You cannot know everything at once, just like you cannot count all of the leaves on the tree."
The brain is even more amazing than I thought. The fact that it can control and create so much without me knowing exactly what is happening is awesome, but a little scary.
