Evil evolution hypothesis

This blog posits that belief in evolution equates to atheism. The reasons boil down to the simple fact that while some theists may also choose to believe in evolution, nobody has come up with a theology that in any way makes sense. How can a personal God use evolution as a tool when it is apparently so random? How can a loving God use evolution when it promotes competition and bettering ourselves by experiencing and avoiding pain? How did sin enter the world if animals were around before the Garden of Eden, and what purpose does Jesus serve in an evolutionary context? What does it mean to have a spirit if animals were around, living and dying, before sin? These are the topics of some of the blogs I have links to.

Here is a theory that allows theists (well, Christians, anyway) to hold theism and evolution: Evolution is the Devil's tool, not God's.

Let us imagine a cosmic battle between Good and Evil (Isa. 14:13,14 and Revelation 12:4), and a wager, that Good could overcome Evil. To this end, Good said to Evil, construct a system of your own design, and I will show that it can be defeated. So Evil thought up evolution -- a means by which ordinary molecules would aggregate and build bigger and more complex bodies. They would eat each other. They would hurt each other. En route they would become sentient, even to the point of recognizing the existence of God, and shortly after such an acknowledgment, they would choose to ignore God -- the definition of sin. (Give somebody free will for long enough and sin's bound to happen eventually). Evolution was Evil's fool-proof plan to demonstrate that molecules could, through natural means, someday transcend their basic chemical interactions and imagine and then discredit God.

Along the way, however, these molecular assemblies of bodies also learned love and Goodness. However, humans continued to show an incapability of avoiding sin. To show that love and Goodness could overcome such inherent evil, God took the form of humanity, experienced a sinless life, and death, the complete human experience. This proved that Evil could be overcome, and now we humans can get that sinless life when we ask for forgiveness and Jesus to live through us.
