Funny, I was under the impression that scientists developed the first fighter planes, jet fighters, nuclear weapons, missiles, bombers, radar for air interception, forensics to find threats, satellites to spy on our enemies, the rockets to get the satellites to space, the radio networks to communicate with the satellites, improved crops to feed the population, and contributed to the increase in education.

So Joe, feel like going back to living in a cave, wearing animal skins that you hunt with your bare hands? (science gave us controlled fires, spears and knives in it's earliest form, so none for you).
