Wow i don't post for a day and everything goes crazy.....
Like i said originally about the dinosaurs its not just the bible that we find these references(although thankyou christina for that Job one)
As for the Flood this is another thing that is not just an idea in the bible infact there are many religions and cultures who tell the story of the great flood. Plus things like soil layering, fossil and other geological structures can be caused by a great flood and instead of taking millions/billions of years these things can be done in a reasonably short period of time.
I think Job was written after the flood however i do not think the bible is never really clear about when these events took place.I will have to go back to Job and have a look at this. Most of the dating etc. comes from people trying to work out the dates from the information given.
Thankyou also for the links you gave a couple of pages back josh on dating methods i will go through them when i get time.
I think you are getting mixed up with some of the things that i am saying however which is probably my fault im not the best at typing out what im thinking clearly. When i say i do not think there is enough evidence for the earth to be 4.5 billions years old im not trying to say that is wrong and the religious look on things is right. infact i feel that there is not enough evidence for the oposite argument either.
The way that i see it though is that unless we have a test over a long period of time for the tests themself like a couple of millenia then it is hard to tell how accurate these methods really are.
