Only man died spiritually that day. God is not unjust or cruel. He did not punish animals for man's disobedience.
So it didn't die at all, and then after the Resurrection it no longer groaned and travailed in pain?
Another reason we know the "death" wasn't physical.
But that isn't right. It's all spelled out right there in scripture Brother. Let's turn to Romans 8, shall we?
18 For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. 19 For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. 20 For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; 21 because the creation itself also will be delivered from the bondage of [f]corruption into the glorious liberty of the children of God.../
Mankind did indeed die spiritually on the day of the fall. But in the spirit is life so it would affect the natural/biological part of life also. It still took Adam 900 years or so to die in the flesh but that's just a testament to how good God's creation was/is. Lol.
Biological evolution is an absurdity. On the other hand, Spiritual evolution is what we strive for and look forward to.
