The bible cannot be used as the basis for any scientific research since it requires faith at a certain point.
Personally, I believe the bible was written at a time when people when came up with mystical reasons for natural phenomena.
As for Noah's Ark, the world was simply not covered in water for 40 days and 40 nights. The mass extinction that would have ensued would not have been recovered from to this day. Not only that, there is simply no record for it. There are records of many parts of many continents being covered at some point, but we are talking about geologic time here. Nothing like that has existed since the end of the last ice age (and a long time before that). Humans and close genetic cousins have been around for a pretty long time, far longer than many creationists believe that even the earth had been around.
Life has been on earth for a few billion years, most of that being single celled organisms whom we have to thank for pumping oxygen it the atmosphere. Complex life pops up about 600 million years ago.
No, man did not exist at the same time as dinosaurs. They are separated by several million years. First of all, the conditions are completely wrong for dinosaurs to exist. All the flora and fauna at that time of the dinosaurs was suited to the same very warm wet environment in which they lived. So, even if you want to say that they were created to be next to man, God would have to have been a complete retard with no understanding of the environment he created. It would be on the level of buying a bowling ball sized fishbowl filling it with saltwater and tossing a koi from a big pond in it. The fact of the matter is that when people from that time saw something they didn't understand, the stories of the creature grew to be far larger than the creature. If man had lived in an environment of any other era than the one we exist in today, they would have either been food for something else or would have had nothing to eat. The reasons you don't see big reptiles around today is that the world is simply just not warm enough for them. Mammals are much better suited to this generally colder climate.
It is a copout argument to say that the earth was created with a history. It is a child-like response to someone bringing you evidence that the past wasn't the way you think it is.
Thank god for the disable signatures option.
