Hi Mark,
You said"all the life on our planet works is miraculous, full of harmonious order, with marvelling beauty."
I agree that nature is beautiful in some circumstances but downright cruel in others and man has no influence on these things. Think of the way animals have to live to survive. They eat each other, not only that but they have some of the same cruel diseases as humans, and some unique to themselves. You blame all bad on man himself, what about natural disasters like earthquakes, volcanoes, tornados, floods, drought, etc. Does God do this because He's miffed about man wanting to use his free will? This happens to not only bad people but those who are loyal, life long worshipers of God. If our worship meant anything to God it would seem he would at least acknowledge it in some way tangible.
Why should all of mankind today be held responsible for what two humans did ages ago? This story doesn't make much sense to me as it makes God responsible for making all the rest of mankind like them, because we have nothing to do with our being born or being sinners.
