Adamic man has only been around 6000 years ago, that is man with a spirit of God-consciousness fully developed and with a soul and spirit that will never cease to exist so that when we die later we shall be resurrected. Pre-Adamic men when they died would simply cease to exist. About 6000 years ago God breathed in the breath of life directly creating man's spirit and when the spirit made contact with the body the soul life was formed so man became a living soul with a spirit and a body. Amen.
The killing that went on before 6000 years ago was indeed sinful as fallen angels and demons corrupted not only earth's earliest ages (e.g. with dinosaurs), but in the restoration (Gen. 1.2) summed up by the six literal days, animals and pre-endemic men killed one another in sin, but God was able to move past this and create a man in His image about 6000 years ago using the body of pre-Adamic man so when God breathed in the breath of life man became a sinless, perfectly created man in His image, placing him in the Garden of Eden. This Garden of Eden was a safe place in the world protected from the outside sin in the world.
God has written the law upon all our hearts and give us all a spirit of God consciousness. We all possess a spirit of intuition, communion and conscience; also, we all possess a soul of mind, will and emotion.
Christopher Hitchens said "We are encoded and programmed." As far as I know anything encoded and programmed needs an Encoder and Programmer. He also said,
"What we risk if we take the supernatural route is the idea of the unchangeable, unalterable authority, one apparently benign, one apparently wicked, both of them eternal, both of them unchanging and unchangeable, and ourselves as their play things, and their objects, and their raw material. This is the idea of the totalitarian. This is the idea of where tyranny begins with the eternal unchanging tyrannical authority where we must guess by our poor powers to guess what is wanted of us, and to spend our lives on our knees. I say the beginning of emancipation is to repudiate this antique serfdom and all the contemptible and often laughable superstitions that requires for its maintenance."I wouldn't say Satan's decision to eternally reject God is unalterable, for at any time he could repent, but alas, he does not and will not.
I don't think God considers us as play things, but He made us in His image fearfully. How are we raw material when God creates us out of Himself?
Satan hostile to God responds just as Christopher does, "This is...totalitarian." Well, you wouldn't exist if God didn't create you the most beautiful angel Lucifer and men.
Why do we need to guess? Jesus proved He is God by His resurrection and even if you never heard of the Bible, you could still take that common grace God gave you to know that by observing the mountains and stars that God created all things. You would know that an infinite regress is impossible because you would have happened already, having had an eternity to do so. And you would know that that which does not exist can't create anything, so the universe can't come from nothing. Therefore, nature needs a cause outside of itself, outside of time and space, and this is whom we call God. Not any God though, but the One True God of the Bible since only Jesus proved He is God.
What is superstitious then is to think the universe always existed or started up from nothing. How silly! How funny! What a funny way to reject God.
