There are so many important discoveries that have been made throughout history! But from a medicine and health perspective, maybe antibiotics. Illnesses that used to kill thousands of people were pretty much eradicated with the discovery of antibiotics, and now simple infections are easy to treat.
Its important we dont have too many antibiotics though, and only have them when we really need them because some bacteria are becoming resistant now (which means antibiotics dont kill them as easily anymore).
