But all that changed in 1961 when a book called "The Genesis Flood" was published. Interestingly, the original publishers, Moody Press, pulled out when they found out about the actual contents, but the company that stepped in, Reformed Publishing Company, found itself very fortunate! They sold 200,000 copies over the next 25 years, and started a powerful movement in some otherwise civilise and rational countries..
The authors, John C. Whitcomb and Henry M. Morris set the cat among the pigeons, and they are widely blamed for re-starting the YEC movement. Fundamentalist home-schoolers refer to this 'scholarly work' in order to justify to their children that their claims are true - which of course they are not. How can the children be protected from such lies though?
One of the worries of the original publishers was that the accepted (but still bonkers) traditions of Day Age Creationism and Gap Theory Creationism were threatened. Indeed they should have been worried because neither of those points of view remain as prevalent as they used to be, especially outside USA.
So where does that leave us? The rational scientific world has been downgraded especially in USA, and people who believe in science when they board a plane lose their faith in it when it comes to estimating the age of the Earth.
So now we are stuck with the pseudo-scientific claims of people like 'The Discovery Institute' who propagate YEC and Intelligent Design. Thank goodness that some people keep an eye on their activities and report what they are up to!
