You're guessing. There is no indication he knew death.
Adam is a chosen son of God in my belief.
No cause to say he had never seen anything die.
No cause to say he was unaware of his own pending demise.
You're guessing again. You're scriptures don't give the impression there were humans before Adam. It hints to it about time you get to the story of Cain. Even that in of itself has it's problems if you're assuming Adam and his family was all brothers, sisters, cousins inbreeding.
Day six...Man as a species.
So?....In your scripture you're god did both....
Since Adam didn't seem to understand the consequences the story makes little sense. Your scriptures show he really had no understanding of (right or wrong).
When placed in the garden, he would have been as any other man.
According to the story it took several hundred years to change that.
No he didn't. He said if you eat the fruit your eyes will be open...knowing good and evil (Gen. 2:17).
"For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil."
Your god confirms this at (Gen. 3:22)
"And the LORD God said, Behold, the man is become as one of us, to know good and evil........"
This means they had no prior understanding of right and wrong.
