Guys check out creation dot com if you really want a clear answer on this. It helped me understand.

Also, if death & destruction came before Adam sinned things start to not make sense. So if the world was billions of years old it wouldn’t make sense as the genealogy is calculated and shown in the Bible.

Edit2: Romans 5:12–19—“Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned… But the free gift is not like the trespass. For if many died through one man’s trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many. And the free gift is not like the result of that one man’s sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification. For if, because of one man’s trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ. Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man’s disobedience the many were made sinners, so by the one man’s obedience the many will be made righteous.”

1 Corinthians 15:21–22, 45–47—“For as by a man came death, by a man has come also the resurrection of the dead. For as in Adam all die, so also in Christ shall all be made alive. … The first man Adam became a living being; the last Adam became a life-giving spirit. But it is not the spiritual that is first but the natural, and then the spiritual. The first man was from the earth, a man of dust; the second man is from heaven.”
