Discovery is somethings that exists but we dont know about it for eg in ancient times people didnt know about fire, dimonds, etc

invention is anything made out of discovered or special things that have just been discovered about which the common people dont know only special scientists know about it. after the thing is made it is socialized so everyone can use it for eg. t.v, a.c, gaming consolses(xbox, ps, nintendo,etc)
