I could go on, but the fact of the matter is, if you use just the bible to map out a timeline it's a little wonky but doable because for over 2000 years its had revisions and edits so that it would make more sense, if you want to really look the history of the world through geology, ice core samples and what not, it'll paint a very different picture.

Also, Ice core samples that go back as far as 800,000 years have atmospheric gasses trapped within, so give a source to determine the make - up of the air, showing consistant level of carbon... directly refuting the AiG site that claimns the air has changed.

«They're talking about the instrumental data which is unaltered — but they're talking about proxy data going further back in time, a thousand years, and it's just about how you add on the last few years, because when you get proxy data you sample things like tree rings and ice cores, and they don't always have the last few years.

He said scientists have been able to correlate changes in atmospheric temperature with changes in levels of carbon dioxide going back more than 500,000 years by analyzing ice core samples and the CO2 bubbles trapped inside.
