So Adam was not present.
That's not what Scripture tells us.......
Genesis 3:1-7 Now the serpent was more crafty than any of the wild animals the Lord God had made. He said to the woman, “Did God really say, ‘You must not eat from any tree in the garden’?”
The woman said to the serpent, “We may eat fruit from the trees in the garden, but God did say, ‘You must not eat fruit from the tree that is in the middle of the garden, and you must not touch it, or you will die.’”
“You will not certainly die,” the serpent said to the woman. “For God knows that when you eat from it your eyes will be opened, and you will be like God, knowing good and evil.”
When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it. Then the eyes of both of them were opened, and they realized they were naked; so they sewed fig leaves together and made coverings for themselves.
Doesn't clearly establish that Adam was standing there, dumbly listening to the Serpent beguiling Eve. Sounds much like the Serpent beguiled Eve, then Eve (changing location) went to fetch Adam, and then ate of the Forbidden Fruit, and then convinced Adam to eat of it, too.
