Polar Shift, Adam & Eve, Noah...all explained, page-4

''According to Chan Thomas, the Bible talks about two(there were more than two from other evidence) extinction events(caused by polar shift). The first, about 11,500 years ago, survivors being Adam and Eve. The second was Noah's flood. He is just trying to put out a more accurate version of these stories.''​

There is nothing in the bible to suggest that A&E were the survivors of an earlier cataclysm. Genesis is specific on the timeline of its creation story, days of creation, etc,​
