That is not Christianity.
It is. It's not the emphasis you choose to put on it, but it's a reasonable description of the story.
Adam or man is the one who spoils the relationship, his legacy.
How can Adam be punished for wrongdoing when he was made with no capacity for understanding of wrongdoing?
Human society is despoiled as a result of it and all humans suffer from the acts of humans who come before....
And yet the societies that have moved away from Christianity and other religions are the ones where the suffering is demonstrably the least.
In order to take sin on himself His humanity is resurrected by divinity.
Why is a blood sacrifice necessary for (unwarranted) forgiveness?
Was Dead now risen from dead.
Three day sacrifice... that was definitely a sacrifice sufficient to fundamentally alter the psycho-spiritual destiny of humanity for all eternity... oh, wait, no, that's a particularly bad Bacardi Breezer bender.
Not magically that would be the case if God just magickly waived the consequences of sin away without taking it on himself.
Was there medical intervention? Was there some sort of first-aid applied? What process was used to reconstruct the broken down neurons which started to degrade with lack of oxygen? Or was this just some divine handwaving... the Resurrection is depicted as one of God/Jesus' miracles, that sort of definitionally makes it magic.
