Denton does not cite anything on the question of "dawn rocks" and so I assume he believes this one to be common knowledge, at least amongst people who study such things.
Let me get this straight: You were betting your argument on what you assume
? If so, this strikes me as lightheaded. No, this one isn't common knowledge among people who study those things. Possibly because "dawn rocks" are not a prediction of evolutionary biology.
One other site I notice which discusses the topic without exclusive reference to Denton is this
... and like the other sites, it gives us no reason to expect that traces of this primordial soup would be present in the geological record billions of years later. Your sources are refuting a prediction evolutionary theory does not make, for all the evidence you have cited so far.
On a more general note, have you ever read a book on evolutionary biology that was actually written by an evolutionary biologist? Or are you going exclusively by creationist summaries of what evolutionary biologists are arguing? If so, would you also ask a Ford salesman for a description of General Motors' vehicles, and choose your car based on his account taken at face value?
