I'm not sure why you're agreeing to a position I don't hold. In principle, I'm not against such an interpretation....of eons....but as I've said, I've yet to hear an argument that has merit, when taken in context to Genesis as a whole.
Some of the arguments stand by themselves when taken out of context, but when you plug them in, they simply doesn't make sense.
That said, I'm not sure why you seem to think that God could not have established such a standard from the beginning, as I remarked on a few posts earlier.
Well then, please forgive me for not paying better attention.
