“Adam didn’t die the day God said he would!”
He certainly did. He died spiritually. The moment he sinned, he became “dead in trespasses and sins” (Ephesians 2:1). Ezekiel 18:4 says, “The soul that sins, it shall die.” It is because we are born spiritually dead that Jesus came to give us spiritual life (John 5:40; 10:10; 14:6; etc.). This is why Jesus told us that we must be born again (John 3:3). When we repent of our sins and believe in Jesus Christ, the Bible tells us that we “pass from death to life” (see John 5:24; Romans 6:13; 1 John 3:14).
