I just reworded the intro.  If you guys don't like the rewording, please tell me why. 

 The sentence "Its exhibits assert that evolution is not responsible for the diversity of life on earth, the planet is just a few thousand years old and that man and dinosaurs once coexisted." 

 Has become: "Its exhibits reject the theory of evolution and assert that the earth and all of its life forms were created in 6 days just 6000 years ago and that man and dinosaurs once coexisted." 

 I like it.  It's still highlights that the exhibits reject evolution yet is more precise about what the museum does assert.
