Lions and Sabre Tooth Tigers obviously were made to kill and eat. Death is part of nature.
I can only agree with your remark. It is true indeed.
However, this is if you are under the impression that the original creation of Adam and Eve was one of feeding and death.
What Jesus clearly say is that Satan brought death over Creation (John 8: 44)
And do not skip over the fact that God told Adam that if he were to eat from the forbidden fruit, he will die.
Well, Adam and Eve were deceived by Satan and they ate from the fruit resulting in them aging and eventually dying.
Look closer and you will see that Adam and Eve did not look as we do today. They were made in the image of God. and God say He is light and covers Himself with light as we cover ourselfs with clothing.
Throughout the Bible we see that God appears as light. He even appeared to the whole of Israel at mount Horeb and this glorious light of God radiated on Moses' face, and this frightened Israel so much, they covered his face with a sheet.
Jesus was Glorified with Light, and even when he ascended to heaven, He changed into a bright light. And keep this in mind, when he ascended into heaven he was without any blood in His body as he told Thomas that a ghost does not have flesh and bone!
His blood remained on Earth.
The first animals that was killed on Earth was when God himself slaughtered animals to give Adam and Eve skin as clothing.
This is the story from the Bible.
Adam and Eve could not die, and were created to live forever.
They did not eat any meat, for their bodies were different from what they changed into after sinning.
They became mortal, with blood in their bodies.
And Romans 8 tells us that the whole of creation grown in pain for redemption of our bodies.
My conclusion is that THE WHOLE OF CREATION changed from a sinless creation where death did not exist, to a creation bound with death!
God did not create death, this was the doing of sin. Satan.
God created life, and will give everlasting life.
Therefore, animals and humans were different from what we are today. No one ate no one.
