This is from Creation: Facts of Life, by Gary Parker who says, "because of the overwhelming weight of scientific evidence, many evolutionists are now calling themselves neo-catastrophists......they agree that most layers of fossil -bearing rock were produced rapidly and broadly by flooding on a catastrophic scale, what Derek Ager compared to 'short periods of terror' in the life of a soldiers.
It's these short periods of terror, it seems that caught plants and animals off guard, buried them too deeply and quickly for them to escape or be obliterated by scavengers, and turned them into fossils.....At Grand Canyon as around the world, the first and deepest layer to contain an abundance of fossil remains is called the Cambrian geologic system....."
This text goes on to say that the Cambrian level is seen at the Grand Canyon (evolution stage 1), but that the next level is Redwall, Mississipian or lower Carboniferous (are you getting all this? :o) .....or evolutionary stage 5.... Stages 2, 3 and 4 (Ordovician, Silurian and Devonian) are missing.
Evolutionists call these 'paraconformities'......meaning, as I understand it, that the other evidence in their view for evolution is so strong that these 'glitches' are nothing more than that......minor irregularities in their theory.
The author's point is that, while there is nothing wrong with drawing that conclusion, it is an act of faith to believe that millions of years of evolution can be seen in the Grand Canyon, because at least 1.5 million years are missing.
There's lots more.....but does that help? I can look for more references because I've heard it from several different scholarly sources (we have a number of books on the subject). These scientists all purport that a catastrophic, universal flood as described in Scripture was powerful enough to have caused the Grand Canyon, the Rocky Mountains, and the separation of continents. It's a theory, of course, but, in my view it jives more consistently with the Bible than evolution in any form.
Let me know if I should keep looking......
