The red button is essential to human existence and civilization.
Hundreds of thousands of years ago, when men were still monkeys in trees, a curious simian saw something red and shiny on the ground. He climbed out of the tree to check it out. It was a small red rock.
In that instant, his mind underwent an amazing leap in insight, dream and desire. He pressed the red rock. His tribe, sensing the unparalleled growth of need beyond mere instinct, also climbed out of the tree, and took turns pressing the red rock.
From that time on, man began the long road of evolution beyond mere tree dwellers into tool makers and users. Our growth as a species is directly linked to an overwhelming desire to make red buttons, just so we can push them.
From our early beginnings as red button pushers, we have learned how to make the red buttons actually do things when pushed.
Today, our advances in science, technology, medicine, agriculture and more, are all traceable to the need to press the red button. The next great leap mankind takes, will be when astronomers discover a red button on a distant planet, causing us to seek and create practical methods of star travel.
Then we will travel to that distant planet, and press the red button.
Edit: Wow! Took me a half hour to come up with all that!
