I understand, but what strikes in in the Gen 3 story is that the garden is described as a divine place where non-natural rules apply. No cruel food chain, men and animals eating every green plant and fruits only [1:29-30] as it will be again on the New Earth [Jes 11:6-7, 65:25], mankind living in the presence of God.
And by their sin they were thrown out of that divine place to the natural place we are all familiar with. Natural rules, death, suffering, natural disasters, sickness, wars, eat or be eaten.
