It's quite simple to believe that god created the world, and yet not believe the word of god to be 100% accurate. (I believe many parts of it are accurate, but certainly not all of it.)

When god made the world, supposedly it was just him and no one else. In other words, man wasn't there to screw it up.

With the bible, man is running rampant on the earth injecting their own prejudices into everything. Or, screwing things up.

Hense my belief that the bible is biased in many places and therefore not 100% accurate.
