God inspires and watches over the writers of His word, I am sure He would not have allowed the basis of many beliefs and the downfall of man to be put in scripture in a inprecise fashion. Everything on creation was specific and with purpose and the story of it was also very important and needed to be told as understandable as possible for man. Otherwise, it would lead to many interpretations, discord and false ideas, but it was given in a clear and orderly fashion that shows you the 'modus operendi' in how God does things. So we must accept Creation as it was given in scripture and God will fill in the extra details when we get to heaven.....
