Adam wouldnt know what death was, the same way you dont know what death is because you never experienced death or at least you have no memory of experiencing death. You as well as adam understand/understood the concept of what death is. You dont have to experience(know) death to understand the concept.
there was no death indicted in the scriptures...of course he didn't experience it first hand, he didn't experience it as an observer either.
Im not sure what you mean by meat. If you mean eating animals there is scripture that says what is food and what can be eaten(Gen 1:29,2:16-17). If you mean something else let me know.
right no animals just fruit...that's why i say, adam hadn't witnessed death as an observer...
Then God said, "I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food.
16 And the LORD God commanded the man, You are free to eat from any tree in the garden; 17 but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die.
They understood the concept of eating from the 2 banned trees was wrong. There is a difference between understanding a concept and experiencing(knowing) it. I gave the example of, you dont have to stick your hand in fire to understand the concept of that is bad, but you wont know it is bad until you experience it.
not that sticking your hand in a fire is bad, it hurts...
once you stick your hand in the fire will you know what being burned feels like
you can UNDERSTAND what the word delicious means but not
until you eat this tasty pastry will you KNOW what delicious is. god held them accountable for something they were not privy to. that is why this story shouldn't be taken literally, that's all.
