Bible

Genesis 1:31 And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.

It was a perfect creation.  There was no death, pain, or suffering of any kind.  The whole creation had not been put into bondage at this time.

It was very good.  Death is not good.

Evolutionists claim that death preceded mankind.  Evolution claims that the way to great complex order is through random chance and death.  Not only is this bad science, but it also denies the fact that death is caused by sin.  Death could not possibly precede sin.

See also Genesis 3:22

It was a perfect creation, but the Evolutionistic story-telling (and that's all that it amounts to is story telling) says that there was not perfect creation.  If we were to believe the Evolutionistic stories, death preceded not only human sin but also humanity itself.  There are many reasons that people tell the Evolutionistic stories.  Some tell them because they want to continue to walk in sin, not giving God full glory and never enjoying the fullness of all of God's benefits.  They love sin more than God.  Some are just ignorant of the facts.  They have been brainwashed by the efficient edu-brain-washing system of the age in which we live.  Others are greedy for government grants that are only available to those who follow the Evolutionistic religious system.  And so, they deny the perfect creation and the Holy Creator.
