When the devil tempted Adam and Eve in the Garden of Eden, he directly contradicted something that God had told them. God had told them that eating the forbidden fruit would cause them to die. But the devil says to them, “You certainly will not die!” Adam and Eve believe him, and they eat the forbidden fruit and… Well, they didn’t die. They lived on for a long time, becoming the first parents of the human race.

So, was God lying? Of course not. Physical death did enter the human family with original sin, even though Adam and Eve didn’t die right away.
