It's interesting that you bring up this example. Much of the knowledge gained by astronomers (Kepler, Gallileo, Coprenicus, etc.) was destroyed by the church. Or they were labeled heretics because they proved the earth was not the center of the universe. This knowledge contradicted the church and the belief that we are the most important lifeform created by God.
The church, and religion in general, do not like science because the more knowledge science provides us, the less significant we seem, and the less important God is. God has always been used to explain the unknown. The more we know, the smaller God becomes. Many people feel threatned by this. That is why you see the fundamentalists fighting to eliminate evolution from biology classes. It threatens their belief system.
