Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned
Adam was the first man created by God the Father, mentioned in the first book of Bible (Genesis), and bible also says that Adam was the first man to sin. With sin coming to this world, death also came. Hence for everyone in this world who has sinned there is death. Now if we say that, we or anyone who has not sinned, does not have to face death... Then I would say that this is an incorrect statement, as all those born in this world have sinned. There is no human being here who had has born and not sinned. Bible also highlights this in Romans 3:23.. Know about teaching from Romans Road
"For all have sinned and fall short of the glory of God"
