Well, since creationists don't agree on exactly what Genesis does mean, I have no idea. You might believe in a 6000 year old world, or old-earth creationism. Or maybe you believe that some form of evolution happened but that it was directed by God and Darwin is an evil mad scientist to propose his theories of natural selection.
Perhaps you should read Genesis yourself and rationalize the difference between the two creation stories in Gen 1:1 and Gen 2:4. Since they have explicit sequence conflicts between them you should enjoy the challenge.
Personally, I think Genesis, like many of Jesus' parables, was never meant to be litterally interpreted. I believe that Genesis says that God is the creator. And I believe that science has done a good job in describing how God did his handiwork, including His most elegant of creations, Evolution.
