A purplexing question for christians

If Jesus died for all sins past, future, present, and paid the price (death) for all sins.

How come humans did not revert back to the Adam and Eve days and live forever, since the wages of sin is death?

And Jesus paid the price for all sins??

Since the price of sin is paid, no more death necessary!!

Another failed false prophecy assumption!!! More typical Buybull nonsense!
