And I suppose you imagine that Genesis was written from first hand accounts soon after the fall? Come on guy the bible does not in any way in and of itself prove creation in a literal sense. Evolution is not unbiblical. In fact, if you want to accept the bible as 100% literal (which is only 1 of the 4 known senses of scripture - ref:
Summa Theological of Aquinas) then you have to admit that a 7 day cycle of creation IS an EVOLUTIONARY process. In other words it was not all created at once but in staged phases of development - and in fact the universe is still expanding and is still being created. Explain that.
Also are you suggesting that Cain & Abel were twins to be conceived less than a year after the fall or that the reproductive cycle of women has also being subject to an evolutionary (or de-evolutionary) process?
