The greatest scientific discovery would have to be medicine and antibacterial soap. Medicine helps us survive a sickness and antibacterial soap helps prevent us from getting sick. Other's would think it was cars or gasoline, but I believe that we could live with out those things and still survive as long as we could now.

I believe that medicine helps us live longer because it helps us survive. Antibacterial soap is a sanitary measure that helps us to not become sick. Medicine also prevents us from getting sick, or sicker.
