Sorry bout that,

1. In reality, there never was that many Dino's.
2. That whole Dino Days thing didn't last long at all, maybe 300 years.
3. Then Gawd told Noah to build *The Ark*.
4. The rest is history.
5. This planet was under water, when *The Flood* happened.
6. The main reason why is that there wasn't any high mountains at the time, just high hills.
7. It wasn't a big deal to flood the planet then, then the Mountains forced their way up along with the land masses.
8. While the other flat land sunk down, so to contain the water.
9. Look all over the planet, Mountains are all over its coastal areas.
10. The mountains brought up the plains as well.
