Humans are idiots. Both Eden and Earth are sandboxes of the final Heaven where the high intelligence angels interact with the low intelligence humans. Eden is to demonstrate the effect of influence from the crafty snake to Adam and Eve, while Earth provides with the resolution.
On earth all (stupid) humans are under the manipulation of the fallen angels that all humans are kept captive under Law (but without their awareness). It means that under the influence of the angels, humans don't stand a chance to possibly pass the Final Judgment of Law to be saved. As enforced by Law, they shall be fully destroyed along with Earth by a flood.
Jesus is the game changer. His one-time sacrifice at a certain point of humanity legitimately changed the standard of the Final Judgment. Humans are now judged by Covenant instead of Law. Humans stand no chance to counter the (fallen) angels in terms of intelligence and strength, however they are given the weapon of Faith. With faith humans can break the chains and to be saved, which the (fallen) angels can do nothing to stop it.
