How the theory of evolution and the bible fit together

Ever since I married a non member (who sinced joined the Church) he made me question my beliefs and why I was a member of the Church of Jesus Christ of Latter Day Saints. I started questioning why I believed in the bible and the Book of Mormon. Then I started analyzing and figuring things out especially the bible and the theory of evolution. I think I got it figured out.
  First of all it took Jesus six days to create heaven and earth and all that is there. My question is, did it take six of our Earth days or six of Jesus' days? His days are different from ours. One of Jesus's days is equal to one thousand of our years so it probably took six thousand of our years to create Earth and everything in and on it. Makes sense.
 Now where does Adam and Eve and the dinosaurs fit in? I have total and complete faith that Adam and Eve were on Earth. But it is very obvious that dinosaurs ruled the world at some point. Then it came to me. How long were Adam and Eve in the Garden of Eden? Because they were immortal, they could have been there for thousand, perhaps, millions of years before they partook of the fruit and were cast out. Now, if they were "cast out" of the Garden of Eden, what was happening outside the garden during that time? Could it be that dinosaurs ruled the Earth outside the Garden? Things that make you go "hmmm".
  That is the "doctrine according to Barb".
Next time I will tell my theory about how The Great Flood fits into the scientific part of the Earth.
