The whole concept of "original sin" is a tool to remove all hope from the earth. You condemn us for not following laws from some alien world, which defy nature. Then you invent some archetype of the perfect slave, "sacrifice" this never-existing entity, then expect everyone to act like this perfect slave. Once it reaches a sufficient level, it is imposed on all of humanity. And it worked--twice. The first time was when the xians (who were persecuted because they were subverting the Romans) got into the government and then persecuted regular people. And this time, they are pushing communism--our freedom is gone.
There is no ransom. We are all hostage, not to any original sin, but to the Pleiades laws that defy common sense. That thing they call a god wants to use us up and throw us away--the whole thing of its taking credit for creating us is another way to take away our rights to live proper lives in accordance to natural law. And, eventually we will all be hostages to Noahide Law--and with no ransom provided against that.
