Limestone constists of calcium, carbon and oxygen. . . The carbon presumably came from carbon dioxide. If you had that much carbon dioxide in the atmosphere to explain all the calcium carbonate we see in limestone . . . it would be toxic. There's just too much limestone. In fact one of the most outstanding geologists the United States has ever produced, Dr. Robert S. Dietz, personal friend of mine actually, a leading evolutionist - he just admitted, he had to throw up his hands, he could not explain how all the limestone on earth came about.
Your emphasis is misplaced. I have never heard of Dietz as being one of the leading figures in evolution, in spite of Walt’s assertion. His credentials and publications in geology are impressive, and that is the field most relevant to the limestone question. If this account from Walt is accurate, the most it shows is that leading geologists admit that there are important questions that they do not have answers to yet. But I know of no field in science that is free from that charge. This is hardly an indictment of sciences belief in an old earth as determined by other means. Dietz wrote on evolution, but I challenge you to show original contributions from Dietz to evolution that were not based within his expertise in geology. This limestone issue is significant to evolution only if it turned out to be indicative of a fundamental error in the other age of the earth studies. Lacking that, I see little applicability to evolution.Limestone consists of calcium, carbon and oxygen. . . The carbon presumably came from carbon dioxide.

I am a little disappointed at what seems to be a retreat on Meert’s part. Meert has a web site that shows that at least some of the claims made by Walt about the exchange are not quite true (for example – that Meert refuses to debate purely on the science). But overall, I fail to see why the scientific evidence could not be evaluated purely based on scientific merit, even if it was prompted by a Biblical belief.To see a report of how evolutionists are too (chicken) to debate Dr. Brown, see: http://www.trueorigin.org/Meert1.pdf
