Genesis 1:30 says that God gave every beast of the earth plants to eat, so we know that the animals which today are carnivorous were not killing for food. There’s no Biblical implication that any other form of animal death occurred—in fact, all Scriptural evidence denies that it did.The text says that God found His creation good. Does “good” include sickness and death in His eyes? We know it doesn’t.
Yep, it wasn't until Genesis 3, verse 21 that an animal death occurred.
