As a result of Adam’s decision to rebel in the garden of Eden, we are all sinners by nature and choice, and have fallen short of the Glory of God.

How is it just to punish all subsequent generations for the wrongdoing of Adam and Eve?

After three days and three nights, Jesus was resurrected

So, God sacrificed himself to himself to absolve us of a sin we didn't commit and which HE decided to punish us for, and then resurrected himself after three days. How exactly was that a sacrifice and why does God require a human sacrifice in the first place?

Whoever came u with this really failed at basic logic.
