The Bible account is clear. God communicated His will to Adam when He
told Adam not to eat the fruit of the Tree of the Knowledge of Good
and Evil. We know that Eve got the message as well. When the Serpent
asked her why she wasn't eating the fruit, Eve parroted what God had
said. "Do not eat the fruit of the Tree of the Knowledge of Good and
Evil, or on that day you will surely die."

The Serpent predicted that Adam and Eve would not die, but that they
would become like God, knowing the difference between good and evil.
Eve ate and gave some to Adam, who ate as well.

What happened next was immediate and far-reaching. Death was born.
Chaos, entropy, labor pains, disease, and human evil became the
Planet's plagues.

God immediately expelled the humans from Paradise. As Eve's extra
punishment, earned by offering to share the fruit with Adam, God
mandated that wives would be forever subject to their husbands. To
this day Eve's male descendants in many cultures enforce that
punishment.

The Bible tells us that neither Adam nor Eve received the knowledge of
good and evil until after they had acted. They didn't know that going
against God's command was evil until after they had taken the bite.
When they disobeyed God, Adam and Eve were no more capable of sin than
a newborn baby is capable of crime.
