Eve was most surprised by the serpent's ability to talk.
Answers
Question;
Why wasn’t Eve surprised when the serpent spoke to her win the book of Genesis?
Answer;
Satan the Devil, using a serpent, fooled Eve into disobeying her Father, Jehovah. Satan made an issue of the fact that God’s human children were not allowed to eat “from every tree of the garden.” It was as if he were saying: ‘You mean you cannot do what you want?’ Next, he told a blatant lie: “You certainly will not die.”
Then he tried to convince Eve that she need not listen to God, saying: “God knows that in the very day you eat from it, your eyes will be opened.” Satan implied that Jehovah did not want them to eat the fruit because doing so would enlighten them. Further, Satan made this false promise: “You will be like God, knowing good and bad.”
