Did animals die before Adam and Eve ate of the tree of knowledge of good and evil?
There was death in the world among the human tribes and the animals ate each other to survive, just not in the Garden of Eden where G-D liked to walk and talk with Adam. Outside of the Garden there was no law of right or wrong, no concept of good and evil, incest, murder, violence, paedophilia, rape, theft were just order of the day, Adam and Eve brought to the G-Dless, Earth’s population, from G-D, The Knowledge of Right and Wrong and of Good and Evil to to teach and govern the people and bring them to G-D.
