The question asked more than any other. "Why?" is the prying reason everyone develops their own inquiry for what interests them. The concept why is a basic one, its basically a tree that branches down into more complicated subjects and "pries" information.
The daily usage of this term is phenomenal and amazing once truly broken down. Major discoveries have been found just by digging deeper using the term why. It also can bring out the most complex realization right before your eyes.
Amazing that the simplest things in life can lead to the most amazing.
