In stating the exact year of the flood, we were actually giving everyone a sneak peak of the information we plan on making available in Volume II. That information is in chapter 14 in The World History Model. It will be on page 17 toward the bottom and will start by talking about a “date of the flood”. The Universal Flood chapter does talk about a celestial body called Sedna on page 496 which may have gravitationally influenced the earth enough to cause a flood approx. 4300 years ago. The exact date of the flood comes from additional research which will be published soon!
