Almost every Watchtower publication we've ever seen begins in the Garden of Eden.
We are told the Earth was created for man. We are told man was given a Paradise and that his disobedience introduced to the world sin and death. Man ruined the wonderful, gentle and peaceful plan of God.
That is the story we are told. But, wait! 
Let us subtract man from the consideration of how things were on Earth by going pre-history and looking at the pre-sin, pre-Fall of Man situation in nature. Before man, before the Fall you would have Earth unsullied by Satan and disobedience and pretty much things would be under the exact nature of what God had created. Right, are you with me?
Okay, what do we find there?
Rampant competition between species locked in a life or death struggle for survival; that is what we find. Weapons and defenses are everywhere evident in thorns, thistles, poisons and such in plants to horns, fangs, claws, armour-plating and venom in animals. Are you willing to look at this NATURAL situation and give your concept of God a big THUMB'S UP?
IS MAN'S SIN the "cause" of a chaos of fang and claw, blood and death?
How long did this eat or be eaten scenario continue? What has science revealed about the length of this godly creation BEFORE man?
We are talking a loooooooooooooooooooooooong time. Millions and millions of years.
Are you willing to say all this competition, this struggle, this orgy of eating, fighting, struggling, swallowing, ripping and bleeding confirms your demand that a GOD is behind the design? What sort of God is this?
Is it any wonder no religious person I've ever met will face this and discuss it without instantly dismissing it and turning a blind eye?
The idea of a sweet, loving, benign Creator who created Earth just for man DOES NOT SQUARE with millions and millions of years of kill or be killed survival of the fittest plant and animal existence. No way.
You have to account for the facts. Even the myth of Genesis doesn't account for the facts. It tries mightily to introduce conflict as the fault of man. But, the Bible writers simply did not know about prehistory and the fossil evidence of countless generations of devoured meat and digested living matter that had come and gone a billion times before they sat down to concoct their tale of the Garden of Paradise and man's inept and insane behavior.
Nope, if you are going to insist there is an intelligent design behind Earth, you have to account for the truth of the evidence, the whole truth of the evidence and nothing but the truth of the evidence. Death, fear, deception, struggle, bloodshed and chaos were all about life in its very nature from the get-go. Man is a late-arrival. You can't blame him for everything. Let's take 2 gardens and look at them. The first garden has a gardener and the second garden has NONE. After the passing of time what would you expect the chaotic overgrown garden to have had? Surely, not a gardener.
